User Manual
SNC50/60 Series
Thank you very much for buying our product ,Please read
thoroughly before using the prouuct
Attentions
The charge regulator is intended for use in photovoltaic systems with 12V or 24V nominal voltages, It shall be used
with vented or sealed (VRLA) lead acid batteries only.
Safety Recommendations:
1.Batteries store a large amount of energy. Never short circuit a battery whatever.
2.Batteries can produce flammable gases. Avoid making sparks, using fire or any naked flame. Make sure that the battery
room is ventilated.
3.Avoid touching or short circuiting wires and terminals. Be aware that the voltages on specific terminals and wires can
be up to double of battery voltage. Use isolated tools. Stand on dry ground and keep your hands dry.
Installation
Please installed in the room, avoiding direct-clearance,
do not install in the wet environment, when use it outdoor,
please install controller and batteries in the same place,
and the batteries installed in the same place, the controller
can measuring the battery temperature, charge
voltage regulation.
Attention：
1. Screws specifications M3 × 10
2. Make sure heat-location were not l blocke

1. Connect sequence 1. --2. --3.
2. Wier size: 50A: Min10mm
60A: Min12mm
3. Grounding the solar system: Be aware that the positive terminals
of the SNC controller are connected internally and therefore have
the same electrical potential. if any grounding is required ,always
do this on the positive wires.

REMARK: Mind the recommendations of your battery
manufacturer, we strongly recommend connecting a fuse
directly to the battery to protect any short circuit at the battery
wiring. The fuse must take the charge controller nominal current:
SNC50 : 100A
SNC60: 120A
