Thanks for posting interesting and informative video, though wish they had touched on system costs, potential savings, and approximate payback period. Makes sense that Zigenergy or PointGuard started with solar and battery storage for off-grid applications, like a remote cabin, where investment is more mandatory than based on cost savings. Also sounds like a great system to have for power outages even when costs may not make sense on a purely financial basis.
In video the home owner stated the battery capacity was 16 kW, but the other guy (electrical video “expert”) mentioned 16 kWh which is likely correct. Either way it’s not a huge system compared to Mach-E battery capacity which puts it in perspective. The issue I would have to decide is that with stationary lithium batteries becoming so affordable, I would be tempted to add more home storage and not rely on the vehicle’s battery. If the vehicle’s battery wears out, replacing may cost considerably more per kWh. Plus early degradation would affect driving range.
When I was without power for an entire week last year it confirmed what I already knew (both technically and from previous outages), which is that without using home air conditioning I can get by just fine with very little power and energy. A simple inexpensive solar system with minimal battery storage would likely suffice most of the time. On the other hand powering my home’s air conditioner around the clock (or even a few hours) would require a huge system, and a car’s battery would not help much when power outages extend for a week. It’s not a simple decision, which is also costly and may not get much use for extended periods.
Given the risk mentioned in video that Ford could pull the plug on entire system at any time, I would not invest in this bidirectional charging. Also, charging an electric car that uses $30~50 a month of electricity at most would make investment too high to be worth it for me. I do like the power backup aspect during power outages though.
Well "plaster" in any case is the right word. Not exactly a thought central to this thread but I have been meaning to say something about how GM designates a vehicle with a distinctive 3d chrome badge-like "Z-71" and Ford "plasters" a decal instead. My son has his second "new" Bronco-first was a manual, another story 🤔- and this new one had a sticker over 60g....same sticker- "proudly" displayed.
