Hello

looking to some clarity and hopefully help a lot of other people.

What does the shutdown, restart and low batt setting (either % or Voltage) actually do to the inverter?

 

Also the Grid start, which is a voltage, what does that actually mean ? 

Lastly batt Empty voltage... What does that do when the battery is at that voltage ? Often it is set to way below even shut down voltage but what happens when that value is hit ?

What does the shutdown,  It switches the inverter off.

restart  When battery has charged to a higher level the inverter switched back on

and low batt setting (either % or Voltage)  It is meant to be a warning that the battery is getting low - much like a fuel gauge reserve fuel light.

I hope my brief indication is correct.

I think you should best view these settings in conjunction with the specifications of a particular battery.

I'm just making these numbers up here, but it's typical/plausible values that you may encounter.

Let's say you've got a battery that defines a warranty or normal operating conditions allowing a discharge of 90% of the available battery capacity.

- You could then choose for argument's sake 10% as the percentage at which the system will shut down.

- Before you've drained to 10%, you could set a warning at maybe 20% discharge so you're not surprised when the system goes down.

- Once you've reached the 10% shutdown value, you would then have to wait until the battery has charged up to a minimum value, let's say up to 30% before normal battery operation will resume. So you don't flip-flop and start/restart all the time around 10%

And the voltage at empty would be when the battery is drained to 0% , but this might not be recommended for your battery, eg. it may reduce the service life or affect the warranty if you allow it to go that low.

Ahhh ok thank you! I thought it was like that but the restart had me as I thought if it saw that voltage it would just restart, not that it had to go into shutdown before looking for the restart voltage to switch on.

 

Thank you !
