Overview

The Growatt SPF 5000 ES is a multifunctional off-grid solar inverter that integrates three components in a single unit: an MPPT solar charge controller, a high-frequency pure sine wave inverter, and a UPS function module.

It delivers 5,000VA / 5,000W of rated power with 10,000VA surge capacity — double peak power for starting motor loads such as air conditioners, pumps, and refrigerators. It operates on a 48V battery system and supports lithium, LiFePO4, gel, and lead-acid chemistries.

The unit can run with or without a battery, and grid or solar input priority is configurable. Up to six units can operate in parallel for capacity expansion to 30kW. WiFi and GPRS options allow remote monitoring.

This model is widely deployed in the Philippines for off-grid and brownout-backup applications.
