Long press of High/Low Charging switch until LCD shows “Set Battery”. 2. Press switch Auto for increment & UPS/Normal for decrement the value of Boost Voltage if required. 3. Press High/Low to change next parameter. 4. Repeat step 2&3 for Battery Low Cut & Grid Charging Current Parameter. 5. Press High/Low to save parameters and EXIT from the same switch. PRIORITY OF SOLAR POWER AS PER GRID POWER 1. If PV Current < 8A, battery will charge from Solar as well as from Grid. 2. If PV Current is between 12A-16A, Grid will be bypassed but no charging. 3. If PV Current > 20A, Grid will be cut by PV till battery voltage below 11.8V. 4. If PV Current > 3A & Batt Volt > Boost Volt, Grid will be cut by PV & load on battery.
