G-Amistar GKF-2012 20A 12/24V - Battery charger controller for photovoltaic systems. This particular controller is widely used for medium-power off-grid photovoltaic installations.

It features LED indicators for the state of the battery (accumulator). Especially suitable for photovoltaic systems up to 20A at 12V. It has a fully protected printed circuit and is very easy to use. Its modern and neat design helps you have a clear view of the status of the photovoltaic system.

At the same time, it constantly monitors the battery status and protects both the battery and the other devices you have connected to the system.

Protection against:

• Overcharging the battery
• Over-discharging the battery
• Incorrect connection to the photovoltaic collector
• Incorrect connection to loads
• Load short circuit
• Photovoltaic collector short circuit
• Overvoltage from the photovoltaic collector
• Reverse current

Features:

• Input voltage: <50 Volts
• Battery: 12 V / 24 V
• Maximum input current: 10 Amps
• LCD display
• Full cutoff voltage: 14.4V / 28.8V +/- 0.2
• Low voltage cutoff: 10.7V / 21.4V +/- 0.2
