Transforming Energy Storage: The 500 KWH Breakthrough Experience

Mr. Sam had a Large industrial scale Solar energy PRODUCTION farm. He was supplying electricity to a nearby off-grid community. He has to convert the electricity from DC to AC for household use. 

First, they installed flat roof panels for energy generation. It was a vast field, so we customized their stands with smart sun tracking. PV SOLAR PANELS were enough to produce electricity. The community no longer needs a fuel generator for electricity power.

This hybrid micro-grid system includes a 250 kW solar PV array, a 250 kW/500 kWh lithium-ion battery STORAGE system, and a control room. Inverter created a micro-grid for POWER SUPPLIES with consistent high voltage.

Staff calculated the required TRANSMISSION line length for the power supply. So now it needs large-scale energy storage systems. It also stores electricity for power supply during the night.

We added 32+ batteries with parallel racking. The MODULAR DESIGN also allows easy expansion of the energy storage solution. Mr. Sam approved it, and it was installed shortly. 

In conclusion, the capacity was enough, but we also added a few extra BATTERY PACKS. Now it provides electricity non-stop for continuous days.
