 I’m trying to design an AC coupled battery backup for an existing grid tied solar system that’s using Solar Edge inverters. I just wanted to confirm a few design parameters. My system is 32 kW. It looks like I would need 2 18kPV hybrid inverters connected in parallel, and at least 30 kWh of connected batteries. I do have a copy of a system schematic using a single 18 kPV inverter. A few questions:

1. Are the component capacities I listed correct?

2. What do I need to know about connecting the inverters in parallel?

3. I have a diesel generator I would like to use with the system only when the grid is down. Can I put this on a transfer switch to disconnect the grid connection and connect the generator in place of the grid input?  If so, what configuration changes if any would I need to make in the inverters?

Thanks in advance

Is there a way to reset it ?

Thanks

I have 2 Growatt MIN-5000-TL-XK inverters and I purchased a EG4 Wallmount battery but I am stuck with the connections.  The EG4 battery came with the AWG0/1 cables but the Growatt inverters have the AWG10 MC4 battery connections.  Did I make a mistake with selecting this combination, or can it still work?  I am concerned with the current the connectors can use.

When the CT coils detect that the grid has lost power, can any power from battery or solar

feed back thru the back feed breaker.  I would expect this to not be possible.  Is there any

documentation to verify this ?

 

Thanks,

Matt

After clicking nearly every company, my head was spinning. In order to help myself I need to be clear what what was my goal first needs to be defined. There are several strategies.   

Q1 Are you to get your bill down to Zero? or to try to make money? 

Q2 Free nights vs buy backs? Which is better?

Some plans offer Free Electricity 8:00pm to 6:00am (So Charge your Batteries and your Tsla or EV do Landry after 8:00pm and use your Batteries and Solar combined to keep your grid usage to ZERO from 6:00am to 8:00pm but rates are higher 20cents or so.

I ended up signing up with TXU Solar Buyback 36 month (60 day free no obligation trial) 12.1 cents 500Kwh 16c 1000Kwh 17.9 2000Kwh. I hear David has the best deals but dont offer service for my zip code. 

 

Feedback thoughts?
