The UPS scenario I am looking for is that the inverter will use battery down to say 30%, then switch to grid. If the grid then goes down, the inverter will go back to battery until a lower, say 10%, battery protecting SOC. Is there an option for that?

Yes.

Continue a bit further down is section 5.7  to "Time of use".  Time of use when activated controls charging/discharging when grid power is present. The setting takes precedence over the battery setting in section 5.6.

 

I have the battery setting in 5.6 at 10% deepest discharge but at 20% between 4 am to 8 am in time of use.

If battery goes down to 20% when grid is active then grid will take over, if grid is inactive then I have another 10% until the inverter stops producing from battery.

You can also charge the battery from the grid at a certain time based on the SOC setting in Time of use.

That is absolutely brilliant. I see you have different settings during the day, so during cloudy days, you will always start the night with 50% batteries.

Just one question, shouldn't your grid charge settings be ON?

What brand of inverter are you using?

thanks for sharing all the useful information!

 

the house and the solar project, well done, congratulation!

i am sure, you and your family will enjoy the new home, and

the new ev-car is also on the way, what can you wish more!

 

all the best to you, regards motdaeng

 

Re the EV car, I'm wondering if there's any solar packages specific to charging a set of batteries during daylight houra and then using that charge in the batteries overnight to replenish the EV car batteries?
