Use Guide

Getting It Working on Site

Set battery voltage to 24V or 48V before connecting the battery bank

Ensure solar array voltage stays within the MPPT input range for the selected model

Configure charge current and voltage via LCD based on battery type

Connect AC loads only after confirming inverter is in inverter mode

Test motor loads with a gradual start to verify surge capacity

Enable power saver mode when the system is idle to reduce standby loss
