Product Description

Solar Battery for Long Life

The solar battery fitted in gamma solar PCU feeds to it at a constant boost charging current until its voltage reaches 14.2V and the float current (which is very close to zero) then maintains this voltage above 13V. Thus reducing the float current (flowing for the longest period during the entire process) becomes zero, which ultimately results in greatly increased battery life and is fully charged simultaneously.

Extensive electronic protection

Gamma Solar PCU which ensures safety, it prevents reverse flow from battery to solar array, it provides load short circuit protection, it provides solar battery through DC fuse, overload protection, input low or high, output low / high or solar panel provides reverse protection.

Utilizes maximum power available from the solar panel

The gamma solar PCU senses the point of maximum power available in the solar panel and charges the battery with this maximum power. Therefore, at any given time the battery is charged with the maximum possible power.

LCD display

It has an LCD display for better user interface that displays battery voltage, current charge, current discharging current, output voltage, output frequency, output load percentage, input voltage, input frequency, solar voltage, solar current and solar energy.
