LG Chem RESU 10k is a lithium-ion battery for residential PV systems, designed to store excess energy produced by solar panels and deliver it when you need it — in the evening, during peak periods or during power outages. It is known for its efficiency, safety and long-term reliability.
Main features:
Total capacity of approx 9.8–10 kWh, with usable energy around 8.8 kWh
Rated voltage: 48 V
Continuous power around 5 kW, with larger peaks over short periods
Compact dimensions and housing with suitable protection for indoor/outdoor mounting
Integrated Battery Management System (BMS) for optimal control, protection and lifetime
Long life with thousands of charge/discharge cycles
In short, RESU 10k is a mature and efficient solution for increasing energy independence in a residential photovoltaic installation. If you want, I can also make you a shorter, more technical or sales-oriented version.

good battery, excellent price ratio quality. It works without problems with the Victron MPPT that I also bought here.

The battery is ok, but the instructions in Romanian would be a plus. Finally I found information on the net.

I've done over 200 cycles since I installed it, with no noticeable drop. The guarantee is great, that gives confidence.

Thank you all in all. The bluetooth application is missing, it would have been useful to be able to monitor from the phone.

I replaced the old lead-acid batteries with this battery. Half the weight, twice the usable capacity.
