HYBRID SOLAR INVERTER INSTRUCTION MANUAL
Please install a circuit breaker to ensure the inveer is able to disconnect
from grid safely. The inveer is integrated with a RCMU, however, an
external RCD is needed to protect the system from tripping, either type A
or type B RCD are compatible with the inveer.
The integrated leakage current detector of inveer is able to detect the
real time external current leakage. When a leakage current detected
exceeds the limitation, the inveer will be disconnected from grid quickly,
if an external residual current device is connected, the action current
should be 30mA or higher.

Note：The backup PE line and eahing bar must be grounded properly. Otherwise, backup
function may be inactive during blackout.
