Solar Charge Controller
1. Safety Information
Read all the instructions in the manual before installation.
DO NOT disassemble or attempt to repair the controller.
Install an external fast-acting fuse or breaker as required.
Disconnect the solar module and fast-acting fuses/breakers near the battery
before installing or moving the controller.
Power connections must remain tight to avoid excessive heating from a
loose connection.
Only charge batteries that comply with the controller's parameters.
The battery connection may be a single battery or a bank of batteries.
Risk of electric shock! The PV and load can produce high voltages when the
controller is working.
2. Overview
The LandStar E/EU series controller is a PWM charge controller that adopts
the most advanced digital technique. It's an easy operation and cost-efficient
controller featured as:
3-Stage intelligent PWM charging: Bulk, Boost/Equalize, and Float
Support 3 charging options: Sealed, Gel, and Flooded
Battery status LED indicator indicates battery situation
Battery temperature compensation function
With humanized settings, the operation is more comfortable and convenient
The USB provides a power supply that can charge electronic equipment
(LS
EU series only)
Battery type and load output can be set via the button
Extensive Electronic protection

.
NOTE:
Do not connect the circuit breaker or fast-acting fuse while
wiring the controller. Ensure that the leads of "+" and "-" poles are
connected correctly.
NOTE:
A fast-acting fuse whose current is 1.25 to 2 times the
controller's rated current must be installed on the battery side with a
distance from the battery not greater than 150 mm.
WARNING:
The controller
has no PV reverse connection protection;
please connect it correctly.
