Thomas:
The name of the product is "Go Power GPR-25 Controller, I have a couple of systems on the island that I live on in Maine. I have had one of these GPR-25 contollers running my orginal system for 5 years and it works fine. When I built a system for a friend I ordered another GPR-25 and that is the one that failed 2 days after it was installed, it may be just a faulty contoller out of the box. I am hoping that when I plug in the replacement thing will work fine again. Alt E is sending me a replacement so there was good response from this web site store Thanks for the info

#2 - Renewable Energy > Technical Discussion: Other > battery protection

I recently purchased a solar system and installed it with the solar panels feeding the controller then the controller feedsing the battery's and the battery feeding the inverter and on inside the house.
Two days after the system was installed the controller allowed the voltage to increase to 19volts until the 3000 watt inverter sensed this overvoltage and shut down the inverter off. Thankfully the battery did not biol over. My question is what is there at solar store to protect the battery's if the new controller fails again. is there a voltage overprotection breaker for 12 volt systems? where can I get it and
