A word of caution:
Be aware of cheap, less capable knock-offs of our model controller that are too basic to properly charge a battery. They will attempt to only turn ON and OFF for the SAME length of time, every time, when your battery is full. This will constantly boil your battery when it's full, not properly fill it, or both. An improperly charged battery will have a short life and cannot be brought back - reducing it to one to two years instead of a 10 year (or more) lifespan! You don't benefit from returning a product after it ruins your system.
A charge controller must operate a relay whether mechanical or solid state (SSRs). The relay turns the charging from your solar, wind, and/or hydro ON or OFF to your batteries. If you have 100 amps of solar charging being turned ON and OFF to your batteries, you NEED to vary the time between the ON/OFF cycles. Our controller has user changeable custom programming that cannot be duplicated by the dime store sellers. Our controller will more slowly top-off your battery by adjusting itself every time your battery is full by increasing the duration of the next OFF cycle by up to 4 increased OFF times.
For example: 5 seconds to 10, then 10 to 20 seconds, then 20 to 40 seconds and will maintain a 40 second OFF time. You can adjust the starting 5 seconds down to 1 or up to 999.
We even went a step further and programmed in a "sweep time" which is a secondary sensing timer that starts directly following an ON cycle. This tells the controller that it has, or has not, been too long before battery charging is needed again. The user adjustable sweep time allows the user and controller to have a wide range of charging times on any size battery bank. We also pre-wire and pre-program our controllers for you to be able to get up and going without becoming an expert.
You're taking a risk with your system by accepting a too-good-to-be-true price or product description. If you're not convinced this is the controller for you, please check our other charge controllers or ask us which one is right for you.
