Why can’t I put the Charge Controller in a Battery Box?
This particular Charge Controller is not weather or water-proof/resistant and is not designed to be used outdoors unless shielded in a dry environment, such as indoors or within a junction box.
What's more, the back of the controller is metal and poses the danger of creating a connection between the positive and negative terminals of a battery. That...wouldn't be good.
Why does the Manufacturer’s Manual say “Equalization is 10 Minutes” but your manual says 30 Minutes?
The Manufacturer’s Manual is incorrect; we’ve contacted them to verify discrepancies concerning Equalization, Boost Voltage and the duration of each. Both last approximately 30 Minutes, not 10 Minutes.
What type of solar panels can be used with this?
Amorphous, Monocrystalline and Polycrystalline rated up to 21 open Volts and designed for 12 Volt systems. Monocrystalline and Polycrystalline are preferred as Amorphous is the least efficient of the three.
Your Warranty states that if the Charge Controller begins to show corrosion, it is covered under its Elemental or Accidental Warranty provision, correct?
Yes - this is a unique warranty only afforded by ONETRUEGEM, LLC; purchasing the same Charge Controller elsewhere will not allow for replacement under such circumstances.
Why was this product discontinued?
The EPRC 12 Volt 10 Ampere Solar Controller was discontinued for sale to offer a slightly better model, supporting longer equalization and 24 Volts. Customers with the 12 Volt-only model will continue to be supported.
