Getting solar installed in the coming months. Going to forego a separate battery pack at this time as our grid is stable for the most part and we've only gone without power for maybe 3 hours one time in the last three years.

Already see that with this combo, the gateway can use solar to power both the home and charge the truck at the same time.

I am interested in knowing whether the SPAN panel can still automatically shed loads. The literature states that it cannot do that with solar only, but it can with a battery. Does the truck meet this requirement when used in conjunction with the gateway? It would be nice to set load priorities and have the panel automatically power those circuits which I deem more important and terminate those that are not.

Get batteries... You will just end up paying more for them later, especially installation costs and permits...

The advantages of battery packs isn't in JUST being available during power outages, but it will also let you use 'cheap solar' AT NIGHT during 'peak' pricing from your utilities...

I have mine setup with 2 Powerwall 3's (27 kWh of storage) and wouldn't likely EVER need that much if our power went out... That would give us a day or two (not counting charging our EVs) of power for everything at home...

BUT, instead we're able to 'charge them up'... during the day and then use THAT power after the sun goes down AND during 'peak' electricity costs... (4-9pm for us)

That also allows us to SELL power back to SCE during that time when prices are about DOUBLE what they are at other times of the day/night... The power we 'sell' to SCE ends up as 'credits' towards our use during months that don't get as much solar (like Jan-Mar for us)...

Also, having the batteries means using BATTERY power when costs are high and when we 'buy' power from SCE it's in the 'off peak' or 'super-off-peak' times...

The Powerwall 3's also have the inverters embedded in them, so less parts as well which means less points of failure... I think each allows up to 6 different MMPTs so you can have 6 separate arrays and track them all separately without adding a bunch of hardware...

It also makes them more efficient (97.5%!!!) when it comes to conversion of solar to "E"...
