The TP-SCPOE-2424-HP High Power POE/Solar charge controllers with dual inputs 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.
It has a built in POE inserter with 24VDC regulated output. They have full electronic protections for short circuit, reverse current, over-voltage, over-charge and over-discharge.
They control the battery charging current to prevent battery damage from overcharging. The Controller accepts up to 2.6A on POE input to provide up to 60W total power capability. It also provides up to 8A on the solar input
The controller gives priority to the solar panel input so grid electrcity consumption is reduced when the solar panel is outputting power sufficient to charge the batteries.
The built-in over-discharge protection and low self consumption ensures the battery is not over-discharged, which greatly increases the life of the batteries.
The load is turned off when battery voltage is 20V and turns back on when battery voltage reaches 22.
