In 2025, the typical cost of commercial lithium battery energy storage systems, including the battery, battery management system (BMS), inverter (PCS), and installation, ranges from $280 to $580 per kWh. Larger systems (100 kWh or more) can cost between $180 to $300 per kWh.
When your inverter refuses to power up, it could be due to a tripped circuit breaker, loose wiring, or a lack of power from the solar panels. Check all wiring connections to ensure they are secure.

An old or damaged battery may not be able to provide sufficient power, leading to low voltage from the inverter. Faulty wiring can also result in voltage fluctuations.
High-voltage inverters generally offer better efficiency because higher voltage means less current, which leads to reduced heat and less energy lost in the wires.
