SR MT2410 Waterproof MPPT Solar Charge Controller For Off Grid
Solar System
Features of SR-MT2410
1. Adopting double crest or multi crest tracing technique,used for
the condition when a part of solar panel is under shadow or parts
of panel isdammage
2. Built-in maximum power point tracking algorithm which could
promote the energy utilization efficiency of pv system.The charging
efficiency is 15%~20% higher than PWM mode
3. It can find out the best working point of I-V curve within 1
minuite,the MPPT efficiency could reach to 99.9%.
4. Adopting advanced digital power supply techniques which makes
the energy conversion efficiency reach up to 97%
5. Four charging stages:MPPT-equalizing charge-boosting
charge-floating charge
6. With current-limiting charging mode.When the power of solar
panel is oversized,the controller will lower charging power
automatically,which enable the system to work under the rated
charging current
7. Have the fault code indication,it helps user confirm the rated
charging current.
8. Various load control methods.could recognize day and night
qutomatically.
9. Various system protection functions.including
over-charge,over-discharge,over-dischage,over-load,over-heat,battery-reverse
connection and short-circuit protection eyc.
Electronic protections:
PV reverse polarity protection
PV short circuit protection
PV over current alarm protection
Battery overcharge protection
Battery over discharge protection
Battery reverse polarity protection
Load short circuit protection
Load overload protection
Overheating protection
Installation and use instruction of SR-MT2410
1. Fix the controller: Fix the controller onto the surface of the
specific place. Keep a certain distance between the controller and
fitting surface to assure heat dissipation
2. Wire preparation: Adopt the wire matching the current,plan the
length of wire, strip 5mm insulation of one side of the controller
terminal and try to decrease the length of the connected wire so
that a reduction in electrical loss.
3. Connect to the battery: connect the battery wire to the
controller firstly, Pay attention to the “+” and “–”, in case of
reverse connection. If connected well, the indicator light will be
on. Otherwise, please check the connection. If reverse connection,
controller will not working but not damage the controller.
4. Connect to the solar panel: Pay attention to the “+” and “–”,
not reverse connect. If ample sunshine, controller will show
charging mode. Or should check the connection is right or wrong. If
solar panel under the sunshine will produce voltage immediately. If
use 24V or more than 24V system, the solar panel voltage will
exceed to body safety voltage, when use please prevent you self
from electric shock.
5. Connect Load:Connected the load to controller,make sure the
current cannot over the rated current, and notice the positive and
negative electrode. Prevent the system from reverse connect.
