Solar Controller 40A

40A Solar Charge Controller 12V/24V Auto, Solar Panel Battery Controller 40Amp Solar Regulator with Dual USB LCD fit for Small Solar System

-40A Solar Charge Controller 12V / 24V Auto work; Max input voltage: 40V; Max PV power 400W /in 12V, 900W / in 24V. With Dual 5V / 2A max.

-Solar Charge Controller 20 amps only suitable for lead acid batteries: OPEN, AGM, GEL and Seal, not for nickel hydride, lithium, Liions, or other batteries.

-Three Load work mode (Settable), 【1-15H】and 【0H】both belong to the light control mode, and the load will turned off at dawn. 【24H】Load output 24 hours (except for battery under voltage) 【1-15H】Load on after sunset and closed after setting hours (turn off load after dawn) 【0H】Dusk to dawn (the load will turned off at dawn)

-For protecting the lifespan of your battery, once the voltage of the battery drop below 9V, the solar controller will turn off automatically. Only suitable for small home solar system,


Parameters:
Batt voltage: 12V/24V auto

open-circuit protection
Overload protection

Warm Tips:
1. Always connect the battery before connect the solar panel, disconnect in reverse order.
2. Make sure your battery has enough voltage for the controller to recognize the battery voltage
3.DO NOT connect any inverters, generator or battery charger into the charge controller. If an inverter is to be connected to the system, connect the inverter directly to the battery.
