3.3 Charging Mode
Depending on actual situation, the charger uses electricity from power grid, PV, or batteries to
charge electric vehicles. The output power of the charger defaults to the rated power, and users
can customize the output power according to their actual needs.
Only the PV power is used to charge the EV. Loads take priority in PV power consumption, the
remaining power will charge the EV.
When the remaining PV power is less than the minimum output power of the charger, users
can set whether to allow the charger to purchase electricity from power grid on SolarGo App
according to actual needs:
• If allowed, the charger will purchase electricity from power grid to meet the charging needs.
• If not allowed, the charger will interrupt charging until the electricity converted by PV exceeds
the minimum output power of the charger, then the charger will automatically start to
charge.

PV priority
NOTICE
• Only applies to the PV-Storage-Charge scenario composed of charger and inverter.
• When using this mode, the inverter's power limit function needs to be disabled, otherwise
the charger cannot function properly.
• If the EV does not support automatic charging, after the charger recovers from the
interrupted charging state, it is necessary to unplug and reinsert the charging plug,then
manually start charging on SolarGo App.

3.5 Functionality
• The charger can be used together with grid-tied or hybrid inverters to form a PV-Storage-
Charging integrated ecological system.
• The charger can be connected with grid.
Applicable for Diverse Scenarios
When the charger is on line, users can control it remotely via SEMS Portal app, and upgrade the
rmware remotely via the device management platform.
Remote Control
Safe and Reliable
Easy to Use and Maintain
• The charger supports operation via commands issued by APP remotely when it is on line.
• The charger supports operation via Bluetooth connected to APP in a short distance when it is
o line.
• The charger supports charging EV directly under Plug And Charge mode.
• Users can check the charger’s real-time status via its indicator.
• Users can check the charger's fault and operating data via APP.
• The ingress protection rating of the charger is IP65, and the ingress protection rating of the
charging plug is IP55. With a high rating, the charger has excellent anti-dust and waterproof
features and can be operated and maintained outdoors.
• To protect the product and ensure a secure running status, the product is integrated with
over voltage and under voltage protection, over load protection, short-circuit protection,
leakage protection, grounding, over temperature protection, EMS protection and protection
against lighting.
WARNING
When using a charger in conjunction with an inverter,ensure the number of phases between
the charger and the inverter is the same. Dierent phases may lead to three-phase imbalance
of the inverter, thus result in limited charging methods of the charger or low-voltage faults.
