How to choose EPS mode?
There are 4 types of EPS modes, they are:
0 – Disable
1 – EPS without bypass：only in the case of power failure, EPS port will have voltage output (basically no standby power consumption)
2 – EPS with bypass：When there is power grid, EPS port will also have voltage output, and when power failure, EPS port voltage will need about 2s for output switch (low power standby power consumption).
3 – UPS with bypass：EPS port also has voltage output when there is power grid, and UPS mode output when power failure, EPS port voltage needs ＜20ms time for switching (high power standby power consumption)
What is needed to pay attention to for the first installation?
After the battery is installed for the first time, you are advised to charge the battery forcibly (for calibration Battery).
- EV Charger
Smart Solar EV Charger
1）When the charger is connected to the power line, the front end must be forcibly connected to a Type A/30mA RCBO.
2）The default Bluetooth name of the charger is AC – {SN last 8 digits}, and the default password is 111111.
3）Installation environment Requirements
-The installation position of charger shall not be close to dangerous positions such as water pipe, gas pipe and steam pipe.
-The charger shall not be installed in places with severe vibration or high temperature.
-The installation position of charger should not be set in low-lying places where it is easy to accumulate water or drip.
-It is recommended that the charger be installed in an environment with sunshade or umbrella.
-A certain space shall be reserved for the installation of charger to facilitate the inspection and maintenance of technicians.
*Including but not limited to the above.
4）The length of the vehicle connector is 5m by default, which can meet the daily charging use. Special length requirements can be customized.
FAQ
- On-grid Inverter
Q. My router is 5GHz. Can l use it to connect the inverter to my Wi-Fi?
Yes, currently all Wi-Fi adapters support 5G/2.4G Hz switching. New routers can open two different frequencies at the same time, and communication is possible if there is only 2.4G Hz.
Q. How can llimit the power feed to the grid?
A smart meter is required, and please set the value of limit in the app Settings-Feed in Limitation.
Q. My inverter had an alarm saying "PV over current", what should l do?
Solar panel power cannot be more than 150% of inverter rated power. For example, a 6KW on grid inverter can connect 9KW solar panels at maximum. Therefore, please check whether solar panels are over installed.
Or please install 9KW solar panels on two MPPTs instead of one MPPT
Q. Why is the LED not lit up?
