Very nice.

Very nice sounds like sugar and spice

Comparison between Pylontech and the named brand.

No prob

Would be nice if the suppliers can state this in their spec sheets as that would be a deal breaker if they do not supply the software.

They can supply software and you can log into it. It uses the same BMS as the Hubble battery and a few on the market. You can just ask them for the software

BMS software is proprietary and bound by copyright laws making it available to competitors would not be prudent BMS software is not open source nor would it be advisable to give full access to the software because users with too little knowledge can break the BMS and Void the warranty just saying 😉

WOW THANKS!

I would sure love to test an array of these! Makes for pretty interesting reading...

I'm going to let a few of my clients know.

Where can I get a brochure?

Best regards!

Awesome I need one.

The software allows you to see EXACTLY what is happeing inside your battery and exactly what the settings and parameters are.
Granted, most users do not need this as they may break things, but for the price point of these products the user should have the option to use their batteries the way they want without restrictions.
Inverter/battery comms is not the only correct way to have your system setup and managed and actually restricts your full use of the battery to protect the so-called warranties/guarantees.

Most of the good battery suppliers provide full documentation and easy access to everything you need to properly and fully use their batteries.

Couldn't agree more. It's similar to having BIOS access on your MB. You the user have the ability to change BIOS settings, but the risk is on you. Go outside the parameters and something goes wrong, your problem. And this is where the Solar Industry should be too. Read the instructions, use the provided access and make your decision whether to touch it or not. But it's a game of power, the manufacturers wish you the paying customer to be their beggar. There is zero transparency on their websites wrt firmwares, release notes of the firmware, how to flash the firmware and the footnote of risks involved.
Don't treat adults like children. The Home Computer industry learned those lessons rather more quickly.

Data sheet is in the main post you can contact us for installer prices

I'm new to this excelent forum and since I use AGM bateries having LiFe will be a big plus, the product looks solid but "Depth of discharge: 95.00 %" means they use magic cells, 1.5C it's nice if you are like my wife that cooks with 2 electric ovens but she cook for more than 5 minutes, makes no sense to me spoil a good meal and at same time overheat the cells.

One member ask the BMS software but how a brand can warranty a product and at same time give a user the means to damage it?

Here is why if you have a 5KW inverter discharge the battery at 5kWh then this 3.686 kWh battery will be able to absorb a charge rate between 0.5C & 0.75C and a discharge rate at 1.5C without tripping the benefits of that is that when you start of on your solar journey you don't have to break the bank with just one 3.686kWh Greenrich Battery because your 5KW inverter can never reach the discharge rates of the battery.

This sounds like the type of battery that could be useful for user the member in the thread below, in search of a halfway decent system for under R80,000.

Let's say a Kodak King 5kW for R11,615 with the Greenrich for R22,793, add R22,000 for approx 3kW of panels, leaving R23600 for brackets, sundries and fitment.

Not sure if it's possible to squeeze that in, but for the money I think it's a fairly capable setup against loadshedding to keep a small to medium home ticking over.

My attempt at a good deed for the day: nominating this member to be a tester from the perspective of an entry-level client who is new to solar.

How does the price compare to 3.5kW pylontechs? I suppose the 1.5C discharge is an advantage over pylontechs.

Not asking for the software code or how it works (trade secrets copyright etc) and not asking for the firmware code either, those are all propriety, copyrighted and not opensource

The comms protocol to read data and manipulate settings is most certainly not copyrighted and should not be top secret and should be available for end users to use as they please.
As stated on my post/reply many battery manufacturers and BMS manufacturers already make that available to the end users, so my choice of battery will always be the ones that I can fully own and control without being held ransom by the manufacturer or supplier.

"can break the BMS and Void the warranty" - Users do that already to their batteries and inverters.

At the end of the day the end user has bought a product that is restricted .i.e. they do not really fully own what they bought.
Similar to cellphones that get locked to networks, and servicing of certain mobile phone brands and or devices by non-approved repairers(courts have fixed or are busy fixing that).
Similar to the motoring industry warranty servicing rules (courts have fixed that already, in SA anyway)

At the end of the day it's going to be the end user who needs to affect the way these companies operate.

Support the ones that are open and allow you full ownership of your purchase

Many make it very difficult or impossible, which is why there are so many forum posts and github projects to help users to OWN their purchased devices/products.

Totally agree with you @WannabeSolarSparky!!! I mean it's the year 2022. However, some manufacturers will just never learn. Unfortunately, once you buy such a product you are stuck. The more open source the better in my book. Another great reason to not support these type of manufacturers. 

 

Interesting but will wait for more feedback

Looks pretty interesting indeed

Wouldn’t buy anything alpha ess as the batteries it power off while house for no real reason. Absolutely hopeless.

I totally agree on the need for end-user to tinker as some installers totally disappear once initial installation is done. Also with time, demand up or down may change & it helps to have such functionality available. I’m also noting there’s only an on/off switch but no breaker on the battery. Just a preference I normally like but with a suitable SPD it may not be a deal breaker.

Hopefully expansion into regional countries will also happen with the necessary support and backup. 

Just a simple question, maybe I missed it.

What is the guarantee period and the guaranteed number of cycles ?

Also need to know the max depth of discharge for the number of cycles ?

Hi Guys so here is another GIVE AWAY!

We are busy with a test and review of the Greenrich 1.5C 3.686 kWh Lithium Battery 

Yes we will be giving one away to one lucky Power Forum Member in a Lucky Draw 

I will post details on how to qualify for this GIVE AWAY soon watch this space!

Sponsored by Elleyhill Power (PTY) LTD

So some information to wet your appetite about these batteries 

Greenrich batteries have been in the market for some time now and so far we have had mostly positive feedback from installer and end users alike.

What makes the battery desirable is the 1.5C Rating this means the battery can discharge at 1.5 times its capacity rating.

Why would that be so great?

Here is why if you have a 5KW inverter discharge the battery at 5kWh then this 3.686 kWh battery will be able to absorb a charge rate between 0.5C & 0.75C and a discharge rate at 1.5C without tripping the benefits of that is that when you start of on your solar journey you don't have to break the bank with just one 3.686kWh Greenrich Battery because your 5KW inverter can never reach the discharge rates of the battery. 

The 3.686 kWh is also inter compatible with the 4.95 kWh Greenrich Lithium if you require to expand to larger capacity.

This Lithium battery is the only Lithium battery in the market that offers true 1.5C discharge ratings. With 1.5C discharge rates, the Greenrich lithium battery has a much higher power output compared to other 0.5C or 1C lithium batteries. 

The cell technology in the battery is LFP cylindrical high density cells which can do up to 2C however for longevity the BMS limits the discharge  to 1.5C and charger rates to 0.5C continuous and boost charge rate for 5 minutes to 0.75C

Battery specifications:

Weight: 41.5kg

Battery Type: Lithium Ion

Nominal Energy: 3686 Wh

Depth of discharge: 95.00 %

Voltage: 51.2v

Continuous Discharge Rate (Normal Use): 5000 W

Maximum Discharge Rate (5 Minutes): 5500 W

Surge Discharge Rate (15 Seconds): 6144 W

Maximum Charge Rate (5 Minutes): 2560 W

Compatible with many of South Africa’s popular Hybrid inverters’ brands.

Built-in BMS that protects the cell from abnormal temperature, current, voltage, SoC, and SoH.
