Operation Guide

Thank You for purchasing another quality GSL Product.

The SR 1212 is a Negative Switched PWM Solar Panel Regulator which is feature rich and powerful for it’s size due to it’s

microcontroller based design with the added bonus of polymer encapsulation making it water and weather proof.

Featuring:

• Operating from panels that are peak rated to 250W

• Very high efficiency, typically over 98%

• Low night time discharge current, below 10mA.

• Selectable multichemistry. For Sealed Lead Acid , Flooded Cell Lead Acid and Lithium (LiFePO4) chemistries. (Note: This

feature is only available on SR1212-2 only. The SR1212-1 fixed for Flooded Cell Lead Acid)

• Simple Status LED Indication (SR1212-2 model only)

• High operating temperatures - Safely work up to 70°C.

• High reliablity due to dual over temperature protection.

• Built in Low Voltage Disconnect (LVD) (SR1212-2 model only)

• Advanced 3 stage automatic PWM charging algorithm

• Use only PV systems with open circuit voltage below 25v and 250W rated peak power.

• Install the unit away from ammable liquids or gases.

• Use wires suitable for at least 15A, but if wire runs are over 3m then larger wires are recommended to limit voltage

drop and losses.

• A battery fuse ( BF ) is always required and must be located as close as possible to the positive battery terminal and

before any other connection. The fuse ratings will depend on the wire size and load but typically a 15A fuse

is envisaged.

• Before connecting always check battery and PV panel polarity & Do not short PV or Load with Battery connected!

• Always check that the correct chemistry setting is used and that the voltage levels are suitable for your specic

battery.

• Only use Lithium batteries with a suitable BMS.

• This appliance is not meant for use by young children.

• During the charging process on a vented battery do not use a naked ame near a battery which may ignite and explode.

• Never smoke or light cigarettes near a battery.

• Do not place tools on top of battery or allow tools to fall on to the battery.

• Always wear eye protection near a charging battery.

• Ensure a “well” ventilated area is used when testing or charging batteries.

• Ensure ventilation is adequate and venting holes are not obstructed.

• If skin or clothing comes into contact with acid, ush the area(s) with water immediately and seek medical attention if

necessary.

Choose a cable size suitable for

your situation.

Low Voltage Disconnect (LVD)

The LVD function of the unit utilized on the GREEN wire is designed to protect the battery from over discharge by dis-

connecting the negative load wire (GREEN) when the battery voltage drops below 11V for over 2 Seconds.

It reconnects automatically when a new charge cycle starts.

(Not Available on SR1212-1)

Note : Dawn to Dusk load operation is available but minimum orders apply, please contact our sales team for more

info on this feature.
