Product Details

China factory 15A 20A 25A 30A 40A mppt solar charge controller

Product Description

Functions

(1) Maximum Power Point Tracking technology

(2) Multi-stage Charge Control

(3) Charge Voltage Temperature-compensated

(4) Discharge Control

(5) Protection against Reverse Connected Batter

(6) Protection against Reverse Connected Solar Modules

(7) Reverse Current Protection

(8) Overtemperature Protection

(9) PV Overvoltage Protection

(10) Current-limited for Excessive Charging Current

(11) Load Output Overload Protection

If the permissible load current is exceed, then the load output is switched off. The overload current vs. duration shows as follows:

Rate of Current	Duration (s)
1.1Irate ≤I< 1.2Irate	120
1.2Irate ≤I< 1.5Irate	60
1.5Irate ≤I< 1.8Irate	10
I≥ 1.8Irate	0.2
Note: Irate=10A, nominal load current

product detailsThe controller restarts the load every 3 minutes automatically, but the user can also restart the load by the Restart key.
