DUO BATTERY 10A charge controller for two batteries
PWM 10 A solar charge controller EPIPDB-COM-10: 12/24 V Auto, maximum PV open-circuit voltage 30 V a 12 V; 55 V a 24 V.
For off-grid solar systems; always verify panel and battery compatibility.
Need a controller for battery charging in an off-grid solar system? The EPIPDB-COM-10 handles up to 10 A on 12/24 V Auto systems and clearly defines the PV-array and battery limits to check.
Choose the controller from module open-circuit voltage, charging current and the battery profile. Cabling and protection devices must be sized by a competent installer.
Why is a solar charge controller required?
Installed between panels and batteries, the controller manages charging and keeps operation within its ratings. PWM requires modules matched to battery voltage; MPPT operates around the array maximum-power point within its range.

Frequently asked questions
Is this controller PWM or MPPT?
The EPIPDB-COM-10 uses PWM technology. PWM and MPPT are not interchangeable: the PV array is matched to the battery differently.
Can any solar panel be connected?
No. Module open-circuit voltage, current and configuration must remain within the ratings; include the cold-weather Voc increase.
Which batteries are compatible?
The declared profiles are: Sealed, Gel, Flooded. Check charging voltages and the battery manufacturer's instructions before connection.
How are the two batteries managed?
It manages a main battery and a secondary output according to the model functions: Adjustable charging split between two batteries. Check the manual for priority and available current.
What is the correct connection sequence?
Normally connect the battery first, then the PV array and finally any loads, always following the manual, polarity, fuse and cable requirements.
