What’s the wiring order of the off-grid system?
1.Battery 2. Load 3.solar panel. EPSOLAR controller has protection for wrong connections during installation. There won’t be damage to the controllers. However, we still suggest user use the controllers strictly following the instruction maMore>>
Why should the controller have temperature compensation function?
As temperature rises, electrochemical activity in the battery increases. Similarly, as temperature falls, electrochemical activity decreases. Therefore, as temperature rises, charging voltage should be reduced to prevent overcharge, as tempMore>>
Is there any lightning protection for solar charge controller?
Yes. Some level lightning protection is provided in the form of transient voltage protection on both the PV and battery connections in all Solar charge controllers. However, if you live in an area prone to lightning, you should add additionMore>>
