# edit to show correct inverter size
I have a technical survey happening soon and the more I look into my needs, the more conflicting things seem
We use 2350kwh per year in a 4 bed detached new build. We are low users. Two young children so the usage will rise eventually. Mrs works from home.
EV on the way (sept)
I’m getting 14 panels (full roof)
6.720 kW Total Module Power
14 x 480 Watt Panels
5,718 kWh per year
7kw inverter
2x Sunsynk 5.1kW ELITE HYB
Battery (1ph) IP65
10.24kWh of Battery Storage
POD point solo 3 EV charger point
£11.4k inc scaffold/ bird protection
It’s likely I won’t be getting the most out of this system and I’ve seen that this may not be good for the battery..
I thought future-proofing and even charging the EV off the battery as well as using an EV tarrif could have benefits.
I could lower the battery to 5kwh and cut some costs today although at some point, adding a second battery is going to obviously cost in labour later.
I guess I’m just needing to know if this bigger battery has a place here. I’m hoping to export some energy to offset the whole price over time and my DNO has approved with no restrictions.
I’m after opinions and if possible, anyone in a similar situation
