48v 200Ah battery storage system is a small storage system for 1–2-person daily use. Battery system total energy rated 10kwh. Different from most of other cheap battery system. OSM 48v 200Ah built in with high quality LiFePo4 cells. Combine with the energy storage system BMS. This storage system come with 20 years+ life design. It probably not covers the entire life. but this battery is the exactly products people wanted. Here is an example for one of OSM customer live in Los angles. Let’s see how is the configuration of his house solar energy system.

“OSM 48v 200Ah solar battery storage system works very stable, I can use a computer to monitor the battery system anytime. In additional, this smart battery system can communicate with my inverter directly, it tells the inverter when to feed it and when to discharge it. perfect !”

Mr. Rajpal Singh use a lead acid battery group before. They are working properly and in good condition, until 2 years later. It seems can’t be fully charged as it is lost capacity during past days. He had no choice and find new batteries to replace it. LiFePo4 is the best, and he find OSM from Alibaba. very easy make an online order.

Residential Battery storage solution


Luxpower SNA5000 serial offgrid inverter can support the system to work as a backup power or a replacement of diesel generator. Since the inverter support paralleling function, the capacity of system can range from 3kW to 50kW. The inverter support working modes. Pure Off-grid working mode: working as a traditional off grid inverters, can set out put to utility first, battery first or solar first.Hybrid working mode: Working as a hybrid, support solar and utility jointly take the load, can set to self consumption mode or charge priority node.

Solar Panels

Rajpal Singh build 2000w photovoltaic array. Apply with 325W solar panel. Totally 6pcs.
