Hi Alison,
Pricing is very reasonable. My only concern is the backup capability of the SolarEdge storedge system. SolarEdge are very good but they are designed as backup system for critical loads only and do not have a generator auto-start control system so this will be a manual operation.
If the manual start generator is not a big concern then this is a great system, however it maybe a little undersized on the PV side.
Goodluck with everything, hopefully the installers do a good job.
Jason.
