Solar Charge Controller Solara SR135TL
User Manual English, Page 2
Low Voltage Disconnect Function (LVD)
The controller has 2 different modes to protect the battery from being deeply
discharged:
1. State of charge controlled: Disconnect at 11.4 V (at nominal load current) up
to 11.9 V (at no load current). Normal operation mode for good battery pro-
tection.
2. Voltage controlled: Disconnect at 11.0 V fixed setting. Appropriate if bypass
loads draw current directly from the battery.
The controller is preset to Mode 1 from the factory. Changing the mode setting is
described below.
In case of doubts which mode to choose, consult your dealer because this has to
be evaluated depending on the battery used.
Settings
The controller can be configured for special operation. For this purpose, open the
cover of the controller by removing the screws on the back side.
WARNING: The controller should not be opened while connected and in opera-
tion!
When the controller is opened, there are 3 jumpers on the electronic board:

General Safety and Usage Recommendations
Intended Use
The charge controller is intended exclusively for use in photovoltaic systems with
12 V or 24 V nominal voltage and in conjunction with vented or sealed (VRLA) lead
acid batteries only.
Safety Recommendations
§ Batteries store a large amount of energy. Never short circuit a battery under all
circumstances. We recommend connecting a fuse (slow acting type, according to
the nominal controller current) directly to the battery terminal.
§ Batteries can produce flammable gases. Avoid making sparks, using fire or any
naked flame. Make sure that the battery room is ventilated.
§ Avoid touching or short circuiting wires or terminals. Be aware that the voltages
on specific terminals or wires can be up to double the battery voltage. Use iso-
lated tools, stand on dry ground and keep your hands dry.
§ Keep children away from batteries and the charge controller.
§ Please observe the safety recommendations of the battery manufacturer. If in
doubt, consult your dealer or installer.

Liability Exclusion

The manufacturer shall not be liable for damages, especially on the battery, caused
by use other than as intended or as mentioned in this manual or if the recommen-
dations of the battery manufacturer are neglected. The manufacturer shall not be
liable if there has been service or repair carried out by any unauthorized person,
unusual use, wrong installation, or bad system design.
