Automatic battery voltage detection for 12V/24V/36V/48V
3-stage charging optimizes battery performance
The MPPT track speed is 5 times faster than traditional controllers
The charging voltage accuracy is ± 0.2V
Overcharge protection, Input PV polarity reverse protection, Output limited current protection, Over-temperature protection
Suitable for battery types such as sealed lead acid, vented gel and lithium battery, etc

Warning and Caution

Be aware that only qualified professionals could install these controllers. Please read full manual before installing
them.
1) The controllers can be installed indoor only. Keep controller away from water. Don't use wet towel to wipe controller.
2) Keep controller in an environmental temperature from -22℃~+55℃. Avoid direct sunlight.
3) Keep good heat dissipation.
4) Use the pure copper wires and connect all polarity correctly.
5) The output is only for DC load less 5A current. If your battery is 48V, then load should be 48V and current less 5A
6) Please don't set any parameters if you are not professional since the controller can work well on default except lithium
battery.
7) Please don't insert any meter or other devices between controller to battery and controller to PV.
8) Please use two-pole circuit breaker. And make sure input and output with separate circuit breakers.

PV Module Requirement

Models: S3-30A, S3-40A, S3-50A, S3-60A V117
Maximum PV Module Power
PV Module Open Circuit Voltage
(Voc of panel should be in the
correct range)
Notes: Voc is 1.5 or 2 times than battery voltage, then it's best efficiency. Please choose the PV modules with right Voc.
