Restart inverter by recycle both AC and DC
switches.
2.
Wait for 1 minute between OFF and ON for
all energy to discharge.
3.
If inverter cannot clear fault, replace inverter.
Protect0070
(Bus imbalance)
1.
Raise limit of IDCmax (for example, 400mA)
to allow inverter more room to adjust in
transient condition to cope with imbalance of
impedance and voltage between Grid
phases
2.
If after adjustment, alarm still occurs, replace
inverter
