Growatt 5kw 48V MPPT Three Phase Solar Hybrid/Off-Grid Inverter

Buy Growatt SPF5000 ES Off-grid inverter

The Growatt SPF 5000 ES is an inverter that can operate both with and without a battery. The maximum input voltage is 450VDC. Integration of an MPPT charge controller optimizes charging and discharging of the battery, making it last as long as possible. Priority can be given to charging via the grid or the connected PV system. The system can also be remotely monitored using a WiFi or GPRS dongle. Parallel scaling is supported.

Inverter solar energy for battery storage

The MPPT charge controller lowers the voltage of panels to the required level to charge the battery. The current is raised with the same ratio the voltage is lowered. This continuously happens during the day to optimize the use of energy. This is dependent on the power of the sun, the angle and the temperature and health of the panels. The charge controller also makes sure the battery will not be overcharged, but also not fully discharged.

Monitoring Growatt SPF5000 ES

A separate dongle allows the inverter to be accessed remotely. There is a WiFi and a GPRS version. Data can always be inspected and priority can be given to either powering from the grid or from the PV installation.

Capacity expansion

The system’s capacity can be expanded up to 30kW by combining a total of six of these units in parallel operation
