KISAE Abso DC-DC Battery Charger System Diagram 2

Wiring Depiction for Powering DC Loads When AC Power is Unavailable

System Overview

KISAE DC to DC Chargers facilitate the charging of a household battery bank from either a solar panel or an engine alternator. These chargers offer dual input capability: an MPPT Solar input and an Auxiliary battery input, providing maintenance-free protection for both batteries and solar panels. Advanced, multi-stage charging algorithms ensure precise charging for Gel, AGM, Flooded, and Lithium batteries, as recommended by their manufacturers, thereby maximizing battery lifespan.

System Benefits

Recharge batteries from two sources (solar panels and engine alternator).
Available in 12V DC and 24V DC versions.
Charges a variety of battery types.

System Wiring Diagram Description

This diagram illustrates the typical wiring configuration for a KISAE Abso DC-DC Battery Charger system.

Components and Connections:

PV Input: Connects to non-regulated fixed or folding solar panels. This input feeds into the DC-DC charger.
Ignition Start: A signal from the vehicle's ignition system (e.g., key switch) is connected to the DC-DC charger, often to enable charging from the alternator.
Alternator Input: The vehicle's alternator supplies power to the DC-DC charger. This connection is labeled "ALTERNATOR to Battery Input".
DC-DC Charger (Model DMT1250): The central unit that manages charging from multiple sources. It receives power from the PV input, ignition start signal, and alternator.
12V or 24V Start Battery: This battery is connected to the DC-DC charger. A fuse is installed in the circuit for protection.
12V House Battery Bank: A separate bank of batteries, also charged by the DC-DC charger.
DC Output to DC Loads: Power is supplied to external DC loads from the House Battery Bank. A fuse is incorporated in this output circuit. The output to the house battery bank is indicated as "Grounded".

Important Notes:

The system features "DUAL DC INPUTS".
Refer to the owner's manual for proper cable sizing.
Installers must ensure the system is installed to meet local code requirements.
For detailed information on fuse protection and wire sizing, please consult the DMT1250 Owner's Manual.
