The unique POESolar charge controllers have dual inputs to charge batteries from a POE source and also a secondary source like solar panels in order to provide redundancy and insure 100 uptime for critical applications. The solar panel input takes priority so that when the sun is shining the grid power usage is minimized. They have five LED indicators to give a quick visual status if current is being supplied by a POE source or solar panel if battery is charging If load output is turned on and a warning if battery is connected with reverse polarity. Solar and Battery Connections are via 5 screw terminals for wire size up to 10AWG. POE Input and Output is via 2 RJ45 shielded connectors. There is a secondary output connector on the back with 5 screw terminals for connecting other electronics to the controller using up to 10AWG wire. This secondary output is equal to the battery voltage except it also has overvoltage protection. The controllers are externally fused with a standard replaceable fuse.Features.
