Hello Powerforum members,

Hubble Energy will be sending me one Hubble Energy AM16+ (16.1kWh) and one AM5+ (5.12kWh) for extended real-world testing and review.

These are part of their current LV Range which includes:

• AM-2 – Popular 5.5kWh 51V NMC battery 1C rating, proven long-term performer.

• AM-4 – Compact 2.56–2.75kWh 25.6V wall-mount battery with 1C rating.

• AM-5+ – 5.12kWh 51.2V LFP with built-in Cloudlink, 1C rating and RGB display.

• AM10+ – Larger 10kWh+ model in the + series with advanced features.

• AM16+ – High-capacity 16.1kWh floor-standing LFP with wheels, built-in Cloudlink and high discharge capability.

• S-100A – 12V 100Ah (1.2kWh) compact lithium battery.

• X-5+ (New X-101) – Newer generation Rack Mounted 5.5kWh model with updated features.

• X-101 – Established Rack Mounted 5.5kWh 51V model, widely used in hybrid systems.

Note:

Hubble Energy also has a very exciting HV Range, but this review will focus 100% on the LV Range especially for members who already own Hubble batteries or are considering them.

Hubble Energy will also soon release the new AM-2+, which keeps the same NMC technology as the existing AM-2 models but adds built-in Cloudlink and several extra features.

My Setup:

• Main system: Solis S6 8kW Pro Hybrid (master) with a Solis S6 6kW Pro seeing the 8kW as “grid”

• AC-coupled: Enphase micro-inverters + Solis S5 4.6kW grid-tied inverter on the Aux port of the 8kW

• 2kW Wind turbine on the Solis S6 6kW MPPT in constant voltage mode

• Separate Solis 5kW Off-Grid inverter for additional testing

• Existing battery bank: 7 × Hubble AM2 (mixed ages – oldest >5 years old)

AM2 cycle counts right now:
1411 | 1036 | 880 | 853 | 805 | 737 | 595 cycles Total bank health still at 99% – very impressive for the age mix.

What I’ll be Testing:

• Daily cycling and performance of the AM16+ and AM5+ on the Solis S6 6kW and the 5kW Off-Grid inverter

• Parallel operation between the new + series and my existing AM2 bank (old model compatibility is a big claim)

• Mixing different aged AM2 batteries and different capacities with the new units

• Compatibility with multiple inverter brands/configurations

• Cross-brand testing – insider info from a senior Hubble engineer says the new Plus range can work with almost any other battery brand

• Full use of the built-in Hubble Cloudlink (I have unit #388)

I’ll also be highlighting the exciting new ergonomic and safety features:

• Wheels on the AM16+ for easy movement

• Magnetic panels that neatly hide all internal cables

• Front-accessible BMS and critical components for simpler maintenance

• Active cooling, fire suppression, and more

The unlimited cycle warranty on these new models is particularly attractive and will be closely monitored during long-term testing.I’ll be doing a detailed initial short-term review followed by ongoing long-term data over the coming months.

Expect real numbers on efficiency, temperature performance, charge/discharge behaviour, Cloudlink functionality, noise, installation, display readability, and real-world interaction with wind + AC-coupled solar.

We will also speak nicely to Hubble Energy and ask if they can provide some products for a lucky draw / giveaway for Powerforum members.

If you have any testing requests (particular charge profiles, high-load scenarios, Cloudlink screenshots, parallel comms behaviour, etc.), please reply in this thread. I’ll try to cover as many as possible.

This should be a very thorough and transparent review for the Hubble community.

Looking forward to sharing the results with everyone.

Cheers, @Powerforum Store

Hello Everyone Just received the Hubble AM16+ and the AM5+ will unbox them this weekend share pics of what's in the boxes. I can however say both batteries are really Heavy already a good sign the AM5+ is almost 60KG and the AM16+ cardboard box almost 160KG wooden crate packaging included... all came on a pallet.

I will need extra hands to move that beast into place the good news is that it has wheels.

Exciting stuff will get some feedback from the Hubble engineer on how to make 3 Cloudlinks talk to each other considering the batteries have their own built in units.

Also get the new batteries to talk to the old AM2 Units...

Then I will start playing around with the batteries and get some meaningful testing done may even be able to share live viewing access to the two cloudlinks with links here on the forum.

Will keep you posted this weekend is unboxing and installing.

Hello everyone

So I have unboxed the Hubble AM5+ Looks very nice comes with the cloudlink and BMS Cables and a set of parallel battery cables.

I will be running it in parallel with my old AM2 batteries so this will be a great test to see how well it works with older model batteries and with different chemistry.

The Cloudlink is they key to make everything work together.

Have not unboxed the AM16+ reason is the battery is seriously heavy almost 160KG so I have had to arrange extra hands for Friday to safely remove the battery from its wooden crate its too heavy for just two people to handle safely without risking damage to the battery or injury.

I am very glad it has wheels because moving it around otherwise would be a challenge.

I will share photos later of the AM5+ and how its configured with the AM2 Units still in process of setting everything up making up battery cable etc.

Hello Everyone

First Impressions are that this is a quality product with very well thought out features to make it easy to install maintain and repair if need be.

So I managed to get the very heavy AM16+ unboxed and upright safely had to get extra hands to help Hubble energy recommends 2 people in reality 3 people are needed the battery is very heavy and you do not want to drop something expensive like this. Once it was on its wheels it became very easy to move around and the wheels are of high quality and has leveling retainers that you use to level the battery when its in the place you need it very nifty in my opinion.

Here is a photo of the AM16+ still in its wooden box you can see the wheels and adjusters clearly and also note the packaging is decent to keep the battery safe in transport.

Here is a picture of the AM16+ Unpacked with all its cables on top of the battery note that there are no hard manuals with the battery everything is available online there are 2 data cables one is BMS the red one and the other is a parallel cable white with 2 x 35MM black and red battery cables. There is also a small L bracket that will allow you to secure the battery to a wall so it cannot fall over or move and a Hubble Energy sticker as part of the accessories.

There are silicone cable access glands where the battery cables and comms cables need to go in and the top cover is held in place by magnets with a magnetic click release all of the crucial components are accessible from the top of the battery including the cloudlink with its antenna and the BMS.

If the BMS needs to be removed for repair or if the clouldink needs to be removed or replaced the main pack does not require to be opened up.

Here is a picture of the top with the cover plate removed where you can see all the ports for the BMS and cloudlink with the built in DC Isolator, reset, power button, binary jumpers, RJ11 terminator, CAN terminator and cloudlink buttons clearly visible and accessible the battery terminals are very robust and there is an earthing point for you to attach your earth cable too.

There is a (Allow Charge/Discharge Dry Contacts) Port a MON port and a expansion port will find out from Hubble Energy what these would be used for out of interest sake.

Also to note the decent Antenna for the Cloudlink wifi comms. There is a gap in the lid cover for the antenna to protrude.

Note the Red BMS cable they provide and the white battery parallel cable also provided. You can run you DC cables through side glands or through the back glands. I assume the provided 35mm Battery cable purpose is solely for parallel configuration. The battery terminals for the AM16+ are M10 not M8.

The Battery is currently connected to my Solis S6 6 KW Pro Version with full BMS communication via the cloudlink and it is currently being charged with wind power only.

Some nice things about the Cloulink is that I can see in close to real time what is happening to the battery so there I can see the Turbine via the S6 6KW MPPT is pumping in around 793W per hour not bad for a 5 to 6 meter per second wind.

The battery was at 39% SOC when I received it now at 52% SOC and charging smoothly.

Note this is a micro grid setup so the 6KW is not carrying any load at the moment it is just charging the battery.

The Data on the inverter does not give such a nice accurate curve because its broken up in 5 Minute segments and the Cloudlink samples every second almost real time.

Before I can get any serious testing done I need to charge both batteries to 100% SOC

My main bank ran down to 16% SOC thanks to a very cold and cloudy weekend so that also needs to get to 100% SOC

Just a reminder I am 100% Off Grid so no utility power to boost batteries quickly.

I have a generator and will use that during the week to boost the batteries if PV and Wind is not sufficient however I want to avoid burning petrol.

I also have a lot of cables to make up for the different tests I plan to run etc.

I will post some info on the AM5 Later however this is also at 39% SOC and needs to be charged to 100% will get to that later this week.

Hi everyone a quick update I had a nice long chat with one of the engineers at Hubble Energy Cloudlink division.

He is going to send me all the required diagrams to parallel the Cloudlink devices between the different battery combinations for my AM-16+/AM-5+parallel tests and also for the AM16+/ AM-2 and AM-5+/AM2 Parallel configurations.

On top of that I will be fully integrating the Solis S6 models with the cloudlink via RS485 daisy chain cable to draw data from the inverters in real time or almost real time every second this will data will reflect on the Cloudlink Portal.

This will give me more in depth real time data to share with you and info on how each battery balances charges and discharges including all the inverter data.

The nice thing about guys that own Hubble's is that if you have the Cloudlink in place you have more realtime remote info and Hubble Energy can do in-depth remote diagnostic on each of your battery packs you simply need to move the cloudlink to the battery you want then to diagnose and batteries in parallel can also be diagnosed to a certain extent as an example they can Identify if a pack has issues or is underperforming which helps a lot if you have a pack that is faulty and need to be repaired under warranty.

Especially the older models that have done some cycles already besides that you can see each packs cycles and all of the info has historical time-lines so you can see when there were heavy loads running off the batteries.

In my case its was quite nice to see with my micro grid setup how well it worked.

In this picture you can see the battery pack of my 8KW Grid Forming inverter not using any power from the batteries basically keeping the pack at 16% while my Grid connected 6KW that sees the 8KW as grid is supporting the loads from the AM-16+ until the sun came up to charge the batteries on the 8KW unit.

And here you can see how the AM-16+ on the 6KW inverter was discharging while the wind turbine was injecting energy into the battery and loads the last bit of the graph the wind turbine was just charging the battery without carrying any loads and later the AM-16+ started servicing loads I set the Battery Reserve to 50% so I hope by tomorrow morning the AM-16+ would have charged more with the wind power.

Some other nice info you can see is state of health battery, serial number, battery firmware versions, battery temperatures with a historical graph etc.

Battery Location the cloudlink has a built in GPS it also supports energy meters for single and 3 phase and some other features that will talk about at a later stage.

All useful info to give you a better picture of how your system is performing.

Here you can see how much charge and discharge your battery actually got in watt.

The first one is PV and the Second one Wind.
