Product Description
Our Advantages
1. It has an efficient MPPT , MPPT efficiency ≥99.5%,and converter
efficiency up to 98%.
2. Charge mode: three stages (constant current, constant voltage,
floating charge), it prolongs service life of the batteries.
3. Four types of load mode selection: ON/OFF, PV voltage control,
Dual Time control, PV+Time control .
4. Three kinds of commonly used lead-acid battery (SealGelFlooded)
parameter settings fcan be selected by the user, and the user can
also customize the parameters for other battery charging.
5. It has a current limiting charging function. When the power of
PV is too large, the controller automatically keeps the charging
power, and the charging current will not exceed the rated value.
6. Support multi - machine parallel to realize system power
upgrade.
7. High definition LCD display function to check the device running
data and working status, also can support modify the controller
display parameter.
8. RS485 communication, we can offer communication protocol to
convenient user's integrated management and secondary development.
9. Support PC software monitoring and WiFi module to realize APP
cloud monitoring.
10. CE, RoHS, FCC certifications approved, we can assist clients to
pass various certifications.
11. 3 years warranty, and 3~10 years extended warranty service also
can be provided.
