The sun: a free natural large nuclear reactor
Hi I'm investigating if it is possible to use a HMS-2000 as a backup Inverter using OpenDTU as management system.
My plan is as follows, one of the 4 solar panels inputs of the HMS-2000 I make switchable between a 50V panel or a 48V LiFePo4 battery. The HMS-2000 will be configured for Zero Export. This means at night one of the solar inputs sees a 48V panel and when the house asks power it will come from this HMS-2000 who is using its battery of which he thinks it's a solar panel. As long the grid is available, I dont see no problems here.
When the grid has a blackout, the HMS-2000 goes to island mode and then no energy is coming from the HMS-2000 inverter. What I would like is to add a transfer switch to the installation that isolates the whole house from the grid and bypass this island mode protection function, so I can continue to use the Inverter function to generate electricity.
My question: is it possible to either bypass/switch off this island mode function, or to find and other trick to make use of the inverter during blackouts. This all given that I make use of a transfer switch to isolate the house from the grid.
Hope someone can tell me more about this.
