Took a bit to find the specs www.dcbel.energy/r16-specs Its a 7.6 or 15.2 kw integrated system. Since the price is starting at 4999, it must be for the 7.6kw system. I didn't do the math on the specs for what the roof can hold for solar.
On one of the pages it compares 4999 to 22000. 1/2 of the 22000 is stationary batteries. Neither scenario includes the nominal rooftop costs. Specs appear to show the allowance for stationary batteries which was my first concern. That of course messes with the numbers above but you need stationary batteries if you want the lights on while you run to the store.
A comparable outback system (all I know well) Outback, FPR-8048A-300VDC, GS8048A-01 Inverter/Charger 8.0 kW, 48 is $7500 shipped. Not as elegant as dcbel but the wiring center that is about 900 of the total cost is a dream to wire. For both systems you're still going to need panels and 2 combiner boxes for an 8k system. My level 2 charger that came with my leaf draws 6800 watts. That only leaves 800 watts for the rest of the house to run while charging. I don't recommend the smaller dcbel unit unless you can remember to use no other heat source while charging including a hair dryer, dishwasher, coffee maker or microwave, etc. Maybe it dials down the charging while you're making toast.
If you work days and charge at work and plug in at night as source battery only, the 7.6kw should be adequate.
The 15.2 kw system is extraordinarily elegant compared to putting two radians together. As streamlined as it is, you will still have an AC raceway with grid in and load out (6 wires including the common and ground) and the DC raceway will have 3 wires coming from each combiner box (2 combiners for an 8k system and 3 or 4 combiners for the 15 kw system) and lastly you'll need a pair of 2/0 to 4/0 wires plus com wire to your stationary batteries.
With an all in one box, your charging station and stationary batteries and inverter combo have to be where your EV can plug in. You'll also want plenty of air flow around any ~16kw system. Generating electricity generates heat.
hey frontrangeleaf, I got my '19 S on 104th street. Complete with the 9k point of sale rebates and the 7.5k federal. I agree that the 240v outlet on the vehicle allows for any inverter with an GEN (generator) input to use the car as a silent GEN to effectively power the home with the car's batteries.
