This is for a residential home.
I install grid-tie PV all the time and have done a half-dozne off-grid before but am not an expert in the off-grid/batteries/grid-tie battery back-up area. Looking for someone who does this daily to help with design, material selection and construction 3-line drawings.Comment

the calculations are pretty easy, the tough part is obtaining accurate homeowner consumption data so the batteries/inverter can be sized properly. And when you add batteries, you need a generator. Then it's a judgement call, simply install a backup generator for $8K, or a battery system for $20K and a $5k generator. Unless the client has / reasonably expects more than a week per month of outage, batteries are a real pain, for the $20K, you can develop a nice fuel storage (500 gal propane tank), and not have to check/add water, clean terminals, have an outbuilding to house batteries.
Batteries are a large step up in costs and maintenance. But for the house at the end of the line, that has the low restore priority, battery backup can make sense,
What certs/qualifications do you require of your contractor?Powerfab top of pole PV mount (2) | Listeroid 6/1 w/st5 gen head | XW6048 inverter/chgr | Iota 48V/15A charger | Morningstar 60A MPPT | 48V, 800A NiFe Battery (in series)| 15, Evergreen 205w "12V" PV array on pole | Midnight ePanel | Grundfos 10 SO5-9 with 3 wire Franklin Electric motor (1/2hp 240V 1ph ) on a timer for 3 hr noontime run - Runs off PV ||
