Other Features

25 kw solar system Lithium-ion based residential energy storage has been around for a couple of years. There are also open concepts that work with most solar battery technologies and any existing grid connect inverter, such as sma solar battery Storage System or any other brand existing retrofit solar system.

-Safety
25 kw solar system are a practical and economical battery system based on Lithium-iron-phosphate technology (LFP or LiFePO4).
-scalable
Available in standard 5kWh modules, the LFP battery modules can be easily scaled in multiples up to 200kWh in a single installation, making them suitable for a range of applications.
-Efficient
Coremax 25 kw solar system feature a round-trip efficiency of 92%, low self discharge rate of 3+ years, and unlike traditional lead acid battery.

This 48v 500ah solar battery bank is scalable energy storage based on 5pcs 48v 100ah CMX48100S. The system include LiFePO4 solar 48v 500Ah 25KWH System and the server rack cabinet.

Flexible use

Tomasa Loforte – March 10, 2024

Hi George,For car starting purpose, it is not recommended to choose LiFePO4 battery.It is better to choose a good car battery, lead acid technology.LiFePO4 battery will not win at instant high current.If for constant current, most of the LiFePO4 batteries can only keep working at 1C current, or maybe lower.This means your 32Ah battery can be working at 32A, 4 cells is 12.8V, the constant power is 409.6W.It seems not able to run your 1.4kW motor and DO remember to get a protection circuit board for your LiFePO4 pack.Andy

I managed to modify the victron software to give higher voltage for all pylontech. Now works fine. Thought you might know. Maybe other customers have same issues.
RENE – February 16, 2023

Rated 4 out of 5
I did have an issue with the new units. The protocol is somewhafferent. First units worked, but were not labeled as ‘pylontech’, but as ‘#.’ or something. Worked. New units get classified as ‘Pylontech batteries’ in victron. But the new batteries don’t get charged passed 47% or 52.5v. Which is the limit for 15s pylontech batteries. These units are 16s, zo require different voltages. But victron keeps the settings locked. Probably a fix coming for it in new beta version.
