Controller charges battery from PV array with higher voltage. Auto-adjusts to 12/24V nominal battery.
Improves energy harvest up to 30% vs PWM & 10% vs slower MPPT.
Locks to optimal MPP even with partial shading, unlike conventional MPPTs.
No cooling fan, >98% efficiency. Full output up to 40°C.
Eight preprogrammed algorithms selectable via rotary switch.
Includes over-temperature, PV short circuit & reverse polarity protection.
Compensates absorption & float charge voltages for temperature.
Automatically adjusts to 12V or 24V nominal battery voltage.
Three-step charging process: Bulk - Absorption - Float.
Refer to section 3.8 for connection details.
Remote control via VE.Direct cable using HIGH (ON) or LOW (OFF) input.
Requires VE.Direct to Bluetooth Low Energy (BLE) dongle.
Read manual, use in proper environment, avoid gas/dust, ensure ventilation, use insulated tools.
Mount vertically, near battery but not above. Use 10mm² or AWG6 cables (max 5m).
Operates when PV voltage > Vbat+5V. Max open circuit PV voltage: 100V.
Connect battery first, then solar array.
System voltage stored in non-volatile memory. Auto-detects 12V/24V systems.
Details of preprogrammed charge algorithms and battery type settings.
Explanation of LED indicators for regular operation and fault situations.
Describes charging cycles and absorption times based on battery voltage.
Configuration of automatic equalization feature.
