The Growatt SPF 4000-18000T DVM-MPV series is a split-phase low-frequency off-grid inverter designed for the US 120/240Vac standard.
With a 48V battery voltage, up to 2× surge power, and a transfer time of less than 10ms, it delivers reliable backup power for residential and small commercial off-grid applications. The series is compatible with lithium, lead-acid, and GEL batteries, and supports optional WiFi/GPRS remote monitoring for real-time system management.
Built-in low-frequency copper transformer delivers 2× surge power for starting heavy loads like pumps, motors, and air conditioners
Supports standard US 120/240Vac split phase output for residential and commercial applications
Built-in MPPT solar charge controller with 60-245VDC range for efficient PV energy harvesting
Compatible with lithium, lead-acid, and GEL batteries with BMS communication for optimal charging
Optional WiFi/GPRS communication for real-time system monitoring via PVkeeper platform
Configurable priority modes, supporting PV, battery, utility, and diesel generator inputs
