The Brat Solar Charge Controller Instructions

Setting up the Brat:

S1 - DIPSWITCH

MODES:

The switch marked as

S1

is used for setting up the

various modes of the Brat. Pushing the switch up turns it

on and pushing it down turns it off.
Switches S1 -2 (Parallel), S1 -3 (1 2/24 Volt), and S1 -4 and

S1 -5 (Battery Profile) are only read on power up of The

Brat. These switches should be set before powering up

The Brat. S1 -1 and S1 -6 through 8 may be set at any

time.

ON

OFF

For lighting / load settings see

S2

on page 1 0.

S1-1 Solar Clock -

When on, The Brat will adjust load control for seasonal solar changes (time).

S1-2 Parallel -

When on, the load circuit is used by the Brat to boost charging to 30 Amps.

S1-3 24V / 12V -

Push the switch up for 24V systems and down for 1 2V systems.

S1-4 Battery 1 -

Selects the type of system battery - See Below.

S1-5 Battery 2 -

Selects the type of system battery - See Below.

S1-6 Deep / Light -

Up allows load to discharge the batteries deeper. Down for normal / light.

S1-7 Auto EQ -

Slide the switch up to enable Auto EQ.

S1-8 PWM DISABLE -

Slide switch up for On/Off charging - Reduces EMI. Not recommended.

S1-4 OFF and S1-5 Off

Sealed Profile #1 Bulk and Absorb 1 4.1 , Float 1 3.7, Equalize NA*.

S1-4 OFF and S1-5 On

Sealed Profile #2 Bulk and Absorb 1 4.4, Float 1 3.5, Equalize NA*.

S1-4 On and S1-5 Off

Flooded Profile #1 Bulk and Absorb 1 4.4, Float 1 3.2, Equalize 1 5.5.

S1-4 On and S1-5 On

Flooded Profile #2 Bulk and Absorb 1 4.4, Float 1 3.7, Equalize 1 4.9.

* Equalization is disabled for sealed batteries.

Using The Brat

:

Now that all solar panels, batteries, and loads (if any) are connected and all mode switches are set it is

time to give the system one last look for wiring errors. When satisfied that all is correct it is time to power

up the system for the first time.

First turn on the disconnect/breaker to the battery. Next turn on the breaker/disconnect to the solar

panels and finally turn on the breaker/disconnect to the loads (if any).

What you should see:

What you should see when you turn The Brat on is the LEDs chasing from left to right and back two

times. After initialization, If there is power from the panels and no errors The Brat would show that it is
