Features
◆ High efficiency MPPT control algorithm, MPPT efficiency ≥99.5%, whole Machine conversion efficiency up to 98%;
◆ Charge mode: three stages (fast charge, constant charge, floating charge). It prolongs service life of the batteries.
◆ Discharge mode: ON/OFF mode, Dual time control mode, PV& Time control mode, PV voltage control mode.
◆ Recommended battery types: Flooded, Sealed lead acid, Gel battery. Other types of the batteries can also be defined.
◆ Most information could be provided by LCD like: system type., PV input voltage, PV input current, day, month, total generating power, battery type, battery voltage, charging current, charging power, discharge current, discharge power and so on.
◆ RS485 communication, we can offer communication protocol also, it’s convenient for user’s integration management.
◆ CE, RoHS, FCC certifications approved.. We can help clients to approve other certifications.
◆ 3 years warranty. And 3~10 years extended warranty service also can be provided.
Electronic protections:
◆ PV over current protection
◆ PV short circuit protection
◆ PV reverse polarity protection
◆ Battery over voltage protection
◆ Battery over discharge protection
◆ Battery reverse polarity protection
◆ Battery overheating protection
◆ Load overload protection
