Good PWM charger for the cost
By Edward Youmans
I’m satisfied with this PWM PV charge controller. Compared to other charge controllers and even those of PWM or MPPT, this one has the best cost. Only around $30 equated to those that do the same and cost around in the $100′s. With PWM techonlogy, the charger is neither on or off like a great deal of of the for less controllers. Instead it regulates the voltage so it is perpetually chargeing and then float chargers when the batteries are full. Also, because the voltage is being regulated closer to the batteries voltage. The batteries do not gas as much. A second thing with PWM controller, the batteries receive pulses of a charge, similar to a battery desulfator. So the batteries plates will not sulfate as much either. I found the charger regualtes the voltage .5V higher than the batteries readings. And float regulate around 13.3V. Controller may handle up to 10Amps (150Watts of PV power) and may control discharge through the controler at 10Amps. Which makes it good for outdoor ligthing or ponds where if the batteries become too low, the controller will mechanically shut them down until the batteries are to the full or entire extent recharged.

Great unit for solar lighting, pumps, fountains and more
By instar
Here’s why this thing rocks:
- good screw terminal connections
- connections for the solar panel, a battery, AND (this is key) a device you want to hook up TO the solar/battery system.
This last point is aweinspiring – it provides a no-brainer way to hook up a device to a regulated / protected solar /battery system, and allows you to use the battery for power when the sun goes down or for the duration of cloudy periods – in fact, the system mechanically delivers power from the battery as needed.
- Also critical is a Low Voltage Disconnect – for a solar fountain project, I initial used another product without the LVD – my battery was drained exclusively overnight, and batteries discharged 100% can’t be recharged effortlessly (they register as an open circuit or cause other problems). This unit takes away that worry.
- The unit has a switch on it so you may turn on/off the device you’re powering right from the unit.
The unit seems to be designed for rural electrification (i.e. remote villages in india necessitating electric lights at night). It has a conformal coating on the circuit board (anti-rust).
For me, I combined a 500 gph Rule bilge pump, this unit, a 30 watt 12 volt solar panel, and a cheap $35 12 volt tractor battery and I have an AWESOME solar fountain. I’m finelooking psyched on this device, and just ordered 2 more.

Excellent controller
By James W. Ross MD
This device does what it says. Has good indicator lights for status and good quality pinch-screw connectors.
There is one point I wanted to mention. IT MATTERS the order in which you hook up the connections to the battery, load, panel, etc.
Follow the instructions on the little booklet. If you hook up out of sequence, the unit will lock up and not run until it is completely unhooked and then powered up correctly!
