Low Voltage Disconnect for Off-grid Solar Power Systems

65 amp Battery Protect

100 amp battery protect

220 amp battery protect

There are some bad reviews for this product on amazon.com but they are silly. I use these battery protect modules for every system I build, and they rock. I think people do not know how to program them because they do not read the manual, and get frustrated. Read the manual for 5 minutes, and program these in seconds. 

Main Features:

• Works with 12 or 24 volt systems (48 volt option available)
• Low Voltage Protection that you can program easily
• Over Voltage Protection (16/32 volts)
• Short Circuit Protection! I use these as a main circuit breaker for my inverters when applicable
• Relay input. Use a programmed relay or use victrons system. Whatever you want!
• Low Current Consumption
• Its cheap! If you consider the price of a high quality circuit breaker or building a diy over/under voltage disconnect system yourself, this is a great deal.

There are a few sizes, and depending on your application will determine what size you need:
