Hubble AM2 / Deye 8KW / Solar Assistant / Hubble CloudLink

Sun, 10 May 2026 10:34:26 +0000

Hi all

I have a Deye 8KW inverter with 2x Hubble AM2 batteries.

Deye connected to Solar Assistant.

Solar Assistant connected to battery #1 via RS232, and the two batteries are connected via link cable.

I also have a Cloudlink lying around here, currently not connected to the Deye as that slot is taken up by the cable to Solar Assistant.

I cannot connect it to the main battery as the RS232 port is linked to Solar Assistant, but I can plug it into the second battery, but then it only sees that battery, ideally I would like it to see both, without losing the connection to Solar Assistant.

Any ideas?

Compatibility of older Hubble AM 2 with newer prismatic cell AM2 batteries

Thu, 23 Apr 2026 14:04:16 +0000

I installed 3Hubble AM-2 batteries together with 3 Sunsynk 5-5k in parallel. All works well. I would like to add one more battery. I hear that the newer AM2’s have prismatic cells which are not compatible with my 4 year old batteries. Is this correct - do I have to source a different battery?

Hubble AM2 mounting position.

Thu, 27 Nov 2025 13:51:44 +0000

Would it be advised to mount two AM2 batteries one above the other but the cable connections face each other?

As in, the bottom battery mounted with the cable to the top and the top battery mounted with cables at the bottom.

I have a narrow space to fit batteries and can fit one above the other but to keep the cables as short as possible.

Hubble Lithium Battery AM-2 5.5kWh

Mon, 10 Jan 2022 07:54:46 +0000

@HubbleLithium
According to the sales data the Hubble AM-2 is a 5.5kWh 51V 100Ah battery:

Nominal Voltage V x Rated Capacity Ah = Wh
51V x 100Ah = 5100Wh or 5.1kWh

Q1. What is the "5HR" mean in "Rated Capacity 5HR"?
A. See http://support.rollsbattery.com/en/support/solutions/articles/216766-what-is-amp-hour-capacity-
Ah is normally determined over 20 hours, unless otherwise specified.
For AM-2, 100Ah / 5hr or 20A continuous for 5 hours - which compared to Lead Acid is very good.
Lead Acid batteries suffer from "Peukert Effect".
Lithium batteries suffer much, much less - See https://battlebornbatteries.com/peukert-effect/

Q2. Is the Hubble Lithium AM-2 a 5.1kWh battery or a 5.5kWh battery?

Multiple Battery Install

Sat, 24 May 2025 15:23:22 +0000

Hi All,

I know battery cable length has been discussed but I need to triple check. I want to connect my second Hubble AM2 to my Sunsynk inverter.

Positive and negative cable from inverter to battery disconnect same length.

Positive from battery disconnect to first battery 125cm

Negative from battery disconnect to second battery 180cm

Negative and positive between batteries 53cm

Sorry for sounding absolutely stupid, cable length need to be the same length, is it the cables between the batteries or the total length of the positive and the total length of the negative ?

Thanks in advance.

Compare Sunsynk 5.32kWh to HUBBLE AM-5 to VOLTA Stage 1 (5.12kWh) lithium battery

Thu, 06 Apr 2023 15:20:51 +0000

The Sunsynk SUNBAT 5.32 kWh battery claims the following warranty conditions: 6000 Cycles @ 80% DOD / 25ºC / 0.5C, 60% EOL.
Does this mean that under ideal laboratory conditions, they measures 6000 cycles under these specific parameters, at a constant rate of discharge of 50% (2.66 kW)?
Does it mean that every time I discharge it faster than at 0.5C, the number of 'guaranteed' cycles drops further below 6000?

Please correct me if I am making any wrong conclusions.

I am aware it is all relative because actual battery discharge rate and depth varies every day, within the limits of the BMS.
However I am trying to compare this battery to the HUBBLE AM-5, which has an even more vague warranty of 'unlimited' cycles for 10 years.
Different manufacturers also state different End Of Life capacity percentages, which makes it even harder to compare a Sunsynk 5.32 with a Hubble-AM5 5.12 or with Volta Stage 1 (5.12 kWh) battery.

From the discharge curves supplied in the VOLTA STAGE 1 guarantee, I conclude the following is true for all batteries, even within the limits set by the BMS:
1.Higher discharge rates greatly reduces long term life (number of cycles).
2.Greater discharge depth reduces long term life, even when limited to 80% of DOD.
3. Higher ambient temperatures means the battery's own working temperature rises more rapidly to a level that reduces the battery 'effectiveness'. This leads to the battery being 'laboured' more, leading to a shorter long term life.

Neither Sunsynk nor Hubble AM-5 supplied discharge curves.

Deye 16kw inverter mixing batteries

Mon, 07 Apr 2025 12:52:14 +0000

Hubble dropping from 38% to 0%

Thu, 19 Jan 2023 18:34:05 +0000

Hi All,

My Hubble dropped for the second time from 30% to 0%. The first time I let it go, but now the second time I'm getting concerned. Has anyone else have this issue? See my graphs attached. Load shedding started at 6pm, then the discharge started.

I'm not too happy with this Hubble battery. (I've had the state of charge % showing wrong on the inverter. It's still showing wrong when I directly connect the battery BMS to the inverter, but via their CloudLink box it seems to work, but then the battery temperature is -100°C. )

RS232 to USB cable for firmware update

Using Solarman risks voiding Hubble Warranty?

Tue, 25 Jun 2024 10:20:52 +0000

Hello,

I am in conversation with Hubble about doing a firmware update to overcome different SOC between two AM-5 batteries connected in parallel.

In the process they have warned me that using the Solarman Smart monitoring app (connected via wireless to my Deye inverter) might void my battery warranty.

This seems a little off to me.

Thoughts?

Are the problems with Hubble repairs getting less and /or resolved sooner?

Wed, 26 Jul 2023 06:47:17 +0000

Does the problems with Hubble batteries and their repair department now sorted or are the still a bit of a hit or miss? Tia

DEYE Inverter and Hubble X100 battery setup

Thu, 23 Mar 2023 17:26:11 +0000

I have a DEYE 5kW inverter that is connected to 2 x X100 Hubble batteries. I have an ethernet cable connected between the inverter and the master battery and another one between the master and slave battery. Can this setup actually communicate between the battery BMS and the inverter or must the setting be for voltage based settings? I am reading mixed documents that seem to state that there is no CAN or 485 communication possible.

Hubble AM-2 Cell failures

Tue, 30 Jan 2024 09:24:51 +0000

About 18 months ago I installed 2 Hubble AM-2 batteries coupled to an 8Kw Deye inverter with 6 Kw panels on the roof with a COC for those that might bring this up. Batteries were never drained below 20% capacity. A couple of months after the installation when everything was working well, I recommended these batteries to my brother who bought five units. A work colleague also bought five units. I can report the following. After 18 months both my batteries have failed with a defective cell. For my brother 4 out of his 5 batteries have failed. For my work colleague 3 out of his 5 batteries have failed. It all starts with a call out fee of R500 for the electrician, who did the installation, to confirm the drop in capacity from 110 ah to ~50 ah. Then you have to pay R500 (which is way overpriced) for the RS232 cable so that the Hubble technicians can log onto your laptop to do a firmware update that will convert the battery from a 5.5kwh to a 5 kwh battery. Once the firmware does not correct the problem you have to have the battery removed and then spend R1000 on diesel to take the battery to Hubble in Joburg, who will then subsequently send it away to Cape Town because there is no welder in Joburg. If you only have two batteries, you will have to do this twice as SWAMBO has now become used to having electricity during loadshedding and two to three weeks without a backup system is not an option. I am not even going to get into the huge electricity bills for the two months... Not to go on a bashing spree I really think that 9 out of 12 batteries failing seems to be excessive?? Although, the support has been all but willing to assist 100% of the costs are for my pocket. It sort of feels like when there is a recall for your car because the brakes were manufactured with a defect, but they require you to carry the cost having them fixed.

RIOT Cloudlink Sunsynk & Deye monitoring

Wed, 25 Aug 2021 11:01:09 +0000

Hi Community.

For those with 8KW Sunsynk & Deye inverters you can now graph all data with your RIOT Cloudlink by simply plugging in a RJ45 cable into the RIOT MUL port and configuring the RIOT RS485 to Deye. Note that some older RIOT units might not support the graphing.

Ensure you have version 3.0 of the firmware on your Cloudlink device. If you do not have this yet, you will have it by next week as we're slowly rolling this out over the next week to everyone. You will then automatically get a upgraded dashboard.

Ensure you set the RIOT as per below if you have Verision 3.0. You can now remote console into your RIOT Cloudlink with the portal.

We are still working on the 5KW Sunsynk graphing and remote control update. We're hoping to release that update soon.

Cloudlink - Is it down?

Updating Hubble Lithium AM2 (old 2021 battery) unsuccessful

Mon, 10 Oct 2022 11:26:44 +0000

I've been trying to get my Riot Cloudlink up and running but the inverter & PV info doesn't show. I checked all connections and they're fine. I contacted Hubble Support who suggested upgrading the firmware on my one battery because it was old and that's where the fun starts. The update doesn't go through despite trying the old and new firmware versions. I'm using the cable from Solar Assistant.

Are there settings on the SunSynk I should be using while trying this firmware update? Has anyone run into a similar problem?

System:
1x Inverter: SunSynk 5.5 KW (M3.3.8.0 / S0.5.1.3 / CE4.2.4
1x Riot Cloudlink: partially online (see pic below)
1x Master Battery: HL210500**** (this is the old one)
1x 2nd Battery: HL220700****

Failed Updates:
1.46: Failed to request MCU upgrade command
2.05: BIN File Error

Battery changed from 120AH to 100AH with new firmware

Tue, 08 Aug 2023 13:37:43 +0000

Afternoon all

In November 2022 I purchased 2X Hubble AM-2 120AH Batteries, these have been working perfectly since.

In June i purchased another 2 AM-2 120AH batteries which were installed yesterday, exact same model.

Now with the new firmware they have all been downgraded to 100ah, but the unit clearly stipulates that its 120AH.

Has anyone else experienced this?

RIOT Cloudlink

Thu, 21 Jan 2021 12:27:31 +0000

Hello Community,

The RIOT Cloudlink is causing a stir in the market currently and we were hoping to announce in the next month more about it, however we have been inundated with questions and we have been asked to release a sneak preview for discussion.

WHAT IS RIOT

RIOT Systems with Hubble Lithium have developed a A.I. comms device that enables the Hubble range of Lithium batteries to have full CAN Bus and Cloud monitoring capability.

The RIOT device is an optional addon to the Hubble X and AM range of products and will allow your Hubble to integrate with almost any CAN bus Inverter including SMA, Victron, Growatt, GoodWE, Sunsynk, Deye inverters on the market. This is made possible by the RIOT CAN bus protocol, which encapsulates 5 CAN bus protocols.

Current Development

The RIOT is in Beta testing to add Axpert and Phocos inverters for full communication and cloud monitoring for the Huble range of Lithium batteries. What this means is that there will be 2 way communication and full integration released in the next few weeks with a firmware update OTA for your RIOT device that will enable full Axpert integration with the AM Range, and X-200 batteries. (The X-100 is not supported for 2-way Axpert integration. Only monitoring).

Whats next?

We will release the Phocos Any-Grid firmware update OTA in the next 7 days for full 2-way integration between the AM-2 and the Phocos inverters. Our partnership with Phocos to integrate the Hubble range of batteries have been a priority since 2020.

14 days after that we should be ready to release Axpert MKSII, VMIII, KING & MAX Protocol firmware updates to enable full 2-way communication.

Where can I get a RIOT?

The Powerforum store will be a distributor of the product.
We are looking forward to their review of the product.

More information will be made available in due course. You can read more here or see a demo of the Cloudlink Dashboard in Action on the following link: https://www.hubblelithium.co.za/riot.html

Who manufactures the Hubble AM-5 battery cells?

Mon, 06 Mar 2023 15:45:33 +0000

Hi,

I tried to email and call Hubble, but nobody I spoke to knows who manufactures the cells in the AM-5 battery. The only confirmation I got was that they are made in China. Have anybody here by chance opened a AM-5 and seen a "by made"| or knows for sure which cells they use? I'm planning on buying the AM-5 either way, this is more to settle my own curiosity.

Hubble Lithium AM2 Battery Settings

Thu, 11 May 2023 12:31:53 +0000

Hello everybody😁 - We just recently had our installation finished with a Deye 12kW3ph inverter and 4 x Hubble Lithium AM2 Batteries.

The folks that did the installation used the AM2 Ver2.0 Manual for the installation, this specifies Bulk/Equalisation Charge 53.8V , and Float Charge 53.8V

I noticed that the batteries have a sticker on the side which has different settings, Equalized Voltage 53.6V , and float voltage 52.6V.

So, I went along to the website which confirmed that the AM2 Ver2.0 Manual settings are the right ones - Bulk/Equalisation Charge 53.8V , and Float Charge 53.8V.

Now that I had conflicting information, I decided to contact Hubble Technical Support just to make sure, which one I should use and they came back with a completely different set of settings, and told me to use Bulk 52.8 , Float 52.8 , so now I have three different sets of settings, and don't know what to believe 🙄.

There is a big difference between 52.8 and 53.8V at the upper end - I'd really appreciate some clarity from those in the know.

Thank you

Hubble Battery with a Deye SunSync inverter

Sat, 28 Aug 2021 09:21:42 +0000

Good day

I have a 8Kw SunSync Deye inverter and two 4.8Kw Hubble x100-48 battery connected in par. My problem is I can’t get my battery to communicate with my inverters though BMS, can anyone maybe help me.

Growatt SPF5000ES with Hubble AM-2 query and Help please

Fri, 14 Jan 2022 13:11:49 +0000

Trust that someone perhaps has more insight.

My system in general works well. However the permanent Battery discharge by the Inverter just doesn't seem right.

The system has been in operation since beginning August 2021. I have since contacted both Growatt and Hubble about this issue and they either don't know or don't want to understand the issue. As soon as my battery is 100% fully charged, it immediately kicks into a discharge, which seems to be the power needed to run the Inverter. The discharge is a round 1% per hour. At 94% the Inverter algorithm then restarts the charge mode and it charges back to 100%. Now if there was no sun that would be normal but this is during the day even when there is excess solar energy. The Solar power powers my 230V requirement, yet the battery still discharges to power the Inverter (anywhere between 42 and 60W)
See attached pics.

All I wish to know if that is just the way that the Growatt has been designed to operate or whether that is an abnormal behaviour of my inverter.

Then there is the matter of the firmware. After my queries to Growatt they sent me 040.05 and 041.05 which I am running ever since. The noticeable change that occurred with this firmware is that the Program codes 12, 13 and 21 are now percentages and not voltages as they were before. There is a huge difference between the two of course.

Neither Growatt nor Hubble have amended their documentation to reflect this change. Hubble has the great Inverter guides and it states to use Protocol52 in Program code 36 which then presets the required values. On closer inspection you will see that Program 12, 13 and 21 are assumed to be Voltage settings which they are not anymore. Now with code 21 that becomes very apparent as your Inverter shuts down when your battery reaches 44% all of a sudden. So that I changed to 20% to prevent the unnecessary shut downs. With 12 and 13 also being percentages now I am not quite sure what the voltage equivalents are for these percentages. They are 47V and 53V respectively, so what are the supposed percentages for these values. And in my case does it even matter as it is an off grid installation, i.e. there is no grid connection on my system.
Appreciate any thoughts or info on this.
