PV and energy storage

How to Choose an Off-Grid Inverter? Off-grid Inverters must have independent energy storage control to directly drive the load and manage battery charging and discharging. When selecting an off-grid inverter, consider the following: ① Rated power: Must match the PV array and peak load power. ② Number of MPPTs: Suitable for complex PV deployments. ③ Charging mode: Supports MPPT PV charging and battery management. ④ Protection functions: Includes overvoltage, overcurrent, overtemperature, and reverse polarity protection. ⑤ Support for diesel generator connection to reduce external equipment.   How to choose between lead-acid and lithium-ion batteries? Lead-acid batteries are low-cost and suitable for budget-constrained and space-constrained applications (such as rural household power su...
