DANGER
• Do not apply mechanical load to the terminals, otherwise the terminals can be damaged.
•
All labels and warning marks should be visible after the installation. Do not cover, scrawl, or
damage any label on the equipment.
• Warning labels on the inverter are as follows:
2.4 Inverter Safety
2.3 AC Side Safety
WARNING
• The voltage and frequency at the connecting point should meet the on-grid requirements.
•
Additional protective devices like circuit breakers or fuses are recommended on the AC
side. Specification of the protective device should be at least 1.25 times the rated AC output
rated current.
•
Make sure that all the groundings are tightly connected. When there are multiple
inverters,make sure that all the grounding points on the enclosures are equipotential
bonding.
•
You are recommended to use copper cables as AC output cables.
• When single overload protection occurs, the inverter can restart automatically; however,
the restarting time will be extended if it happens several times. For a faster restarting, try it
via WE MateApp .
•
BACK-UP function is not recommended if the PV system is not configured with batteries
