Sunsynk DC on/off switch

Featured Replies

Hi..

We need to move PV panels.. Is there steps to switch the PV off and on. And can we switch DC off without shutdown the system so there will still be power for house?

Going to assume you have a sunsynk as i have no other info to go on apart from your image. Yes you can switch PV off on the PV switch on the inverter. You can then drop / switch off the PV breakers in your PV box - this should then render the panels inert. Remember to disconnect the MC4 before starting the work on the panels. The Inverter + batteries will still continue to power the house should eskom drop

@Steve87 - anything else I've left out?

just for clarification -

Edit:
Shutdown process:

1. Flip the Change Over Switch to Grid (To power the house from the Grid and bypass the system) - only if you want house running off ESKOM only - ignore if you still want the inverter to be on
2. Flip the Inverter breakers Off in the DB Combiner Box (same as above)
3. Flip the PV (DC) Isolator on each Inverter Off then switch off DC at inverter

PV is now safe to work on.

Startup process:

1. Flip the DC switch on inverter to on then PV (DC) Isolator on each Inverter On 
(WAIT for the system to startup and Normalize, at this point you will see the DC(if during the day and you have panels) and AC lights. The NORMAL light can take 60-120sec to illuminate you will hear the relays when this happens.)
