48
Volt 20 watt solar charge controllers for wireless Ethernet and WiFi installations
These 48 volt solar charge controllers are made specifically for small, low
power wireless Ethernet and WiFi installations. They use energy harvesting to extract as much energy as possible from a nominal
48 volt solar panel, to charge a 48 volt sealed lead acid battery. The output of the battery is also controlled so when the
batter gets too low in voltage the power is cut off. When the power returns the unit will turn back on.
Accumulate and dump PWM energy harvesting algorithm.
Electronic Overcharge Protection & back current blocking to PV panel.
Low voltage battery disconnect and reconnect at DC output.
All switching is done solid-state, no relays are used.
