Solar Inverters & PCS

PowerKeep solar inverter manufacturer: string, hybrid, off-grid and three-phase solar inverters plus energy storage PCS for residential, commercial and utility PV+storage systems.

PowerKeep is a solar inverter manufacturer and energy storage PCS supplier. Our solar inverter line covers single-phase and three-phase string inverters for rooftop and ground-mounted PV, hybrid solar inverters that combine PV, battery and grid in one unit, and off-grid inverters for standalone systems.

A hybrid inverter manages solar, battery and grid intelligently — charging home batteries from PV, switching seamlessly during outages, and enabling self-consumption. For larger systems, our three phase inverters and string solar inverters from 1000V to 1500V handle commercial and utility PV+storage.

Our energy storage inverters (PCS) support AC and DC coupling, grid-forming and grid-following modes, and work with our containerized BESS. As a solar inverter manufacturer and PCS supplier, PowerKeep provides complete inverter + battery + system design support for installers, distributors and EPC contractors.

FAQ

Hybrid vs off-grid inverter: which do I need?

A hybrid inverter connects to the grid, manages solar and battery, and provides backup during outages — best for homeowners with grid connection and batteries. An off-grid inverter runs entirely independent systems, ideal for cabins, remote sites and regions with unstable grids. PowerKeep offers both, from 3kW to 150kW.

What is a three phase solar inverter used for?

Three phase inverters are for larger PV systems — commercial buildings, factories and utility projects with higher power demand — because three-phase output distributes load evenly and supports larger capacity. They range from 10kW to 150kW in our line.

What is PCS in an energy storage system?

PCS (power conversion system) is the bidirectional inverter inside a BESS that converts DC battery power to AC grid power and vice versa. It controls charging/discharging and grid interaction. PowerKeep supplies PCS for residential, C&I and containerized storage from 50kW to MW scale.
