I've purchased, but haven't installed, a Multiplus 24/2000 to connect to my pv system.
I'm concerned that it'll backfeed the grid and have read there's a setting which when changed will allow backfeeding the grid.
Is there a way to prevent it from backfeeding the grid even though the "mains" has no power? (LOM)
Thank you
LOM is there to prevent exactly that.
No mains, No feed in.
Anyway, unless you install the ESS assistant backfeeding cannot be selected.
That's good. Is LOM a setting? If it is then is there an internal relay which will completely disconnect AC wires that might be able to back feed?
I think I found the answer and hope this applies the Multiplus-
LOM is an automatic process that detects a loss of the mains/network/grid supply. After the detection, the inverter/charger will open its back-feed relay, making sure there is no live AC voltage on its AC-inputs, and anything connected to these inputs.
Unless you plan on using ESS, back feeding is not even a possibility. Even with ESS back feeding can be disabled.
if you do not enable ESS, you cannot feed in. 2 print screen from the ESS configuration.
Even if you enable ESS, you can restrict feed in to the grid / to the AC IN
By default, your Multiplus will not feed in to the grid. Don't worry, be happy and connect it.
