12V/24V, 20A Solar Charge Controller for LiFePO4 Batteries (SC-122420JUD)

  • $49.99

Bioenno Power 12V/24V, 20A Solar Charge Controller (Model SC-122420JUD) is a versatile controller for use in solar systems with an integrated LCD display, that is designed to charge LiFePO4 (Lithium Iron Phosphate) batteries (and AGM/SLA batteries)! This solar controller accepts either 12V/24V input from solar panels and can handle up to 20 Amps. Featuring our proprietary CC/CV (Constant Current/Constant Voltage) circuitry, the solar controller provides a regulated voltage output for charging 12V or 24V LiFePO4 (and AGM/SLA batteries). The solar controller also provides a regulated 12V or 24V output for electrical loads (depending on whether a 12V or 24V battery is used). Solar controllers are required for all solar systems in order to maintain a regulated output voltage to charge batteries and for maintaining a regulating output voltage for loads.

Please note that for any solar setup in which you are using a panel in conjunction with a battery and/or a load a solar charge controller is absolutely necessary. DO NOT plug a panel directly into your battery or your load!

This controller does not boost voltage from the solar panel, but instead will regulate a high panel voltage from 50V downwards.
