Overall Rating: 
Description: The Brunton Solar Controller 12v Battery Charging Monitor is an helpful tool to help you avoid overcharging your 12-volt batteries. The manufacturer says that once connected you can charge your 12v battery nonstop for days. The controller will cut off the power when charging is complete. It’s also good for maintaining the battery in its fully charged state (i.e. RV parked for days or boats). It’s compatible with most of the solar panels (of different brands too) available.

Not so impressive but compact and useful
The controller is easy to install and provides an indication of “charging” or “charged”.
Nearly 30 dollar is a good price considering the quality of this tool and cost savings of not having a “fried battery”
It measures 3.8 x 1 x 2.7 inches; weighs 4.2 ounces.
Before you attach it to the battery both the CHARGING and BATTERY FULL light will be on. Once you hook it up to the battery it works well. It looks very standard in its construction. Versatile for every solar panels.

Sir,
I am in solar power unit design field. Just beginner. Please reply what is the thumb rule to select solar charge controller. As for example 600 Watts is connected load. Here in India it is 230Volts. We select solar panel 600Watts x 1.25% =750 Watts.
Accordingly Battery selected 750Watts / 12 Volt =62.5 Amp Please inform method of calculation to select solar charge controller between solar panel & Battery.
Further, I shall be thankful if you will please inform the complete technical data, information to design solar power supply unit as for example 1000 Watts connected load. Then how solar panel,charge controller,battery,inverter selected? Your guidance and information is valuable to me.
Thanks

Would the Brunton Solar Controller work for a 36 volt golf cart system,, I am getting ready to put a 15 watt solar panel on my golf cart roof
hi, I got a 15w brunton solar panel and the 7w regulator. I hooked it all up and I don’t get any lights to come on in my regulator. I first thought the regulator was bad and got another one but still nothing. I have power from the panel, the included light tester comes on when I plug it in. any thoughts or suggestions on what could be wrong
We have a 12 vol DC Flojet water pump we use to water our livestock from a pond. The pump draws 7 amps. It is connected to two Siemens 50 solar panels, 100watts, 7amps, which charges a 12 volt marine battery. We have used the B-Z mini charge controllers and a Sun. They overcharge the batteries plus do not have a low voltage disconnect, LVD. Do you have a charge controller that is more reliable? All the controllers we have used quit working after a couple years. The B-Z look like something got hot on the back side. Epoxy appears partially melted. Why??
sir;
kindly send me the complete technical data and information to design the solar system
thanks and regards
