Considering Home Energy Storage

We recently purchased a tear-down with the goal of building a new passive house on the lot. Naturally, there will be will be a massive solar array on the house, and probably on the detached garage as well. Picking a panel fairly easy because the differences in PV (photovoltaic) products seems to mostly come down to warranty period. Energy storage […]

GM grabs a hammer, Tesla hands over a nail

First it was Ford, now it’s GM. The not actually a standard “North America Charging Standard” (NACS) connector used by Tesla, has put another nail in CCS’s coffin. Now that GM is on board, 70% of the US EV market is committed to NACS. Most of my thoughts around this can be found in the post about Ford’s action, so […]

Huh? Fancy that… Net Metering Isn’t a Scam…

I’ve weighed in on the Net Metering debate before. So my opinions, which I like to think have a decent foundation in the facts, even though I clearly have some bias, aren’t exactly unknown.

There are procedures around how standards get made, and Tesla didn’t do that. That’s not always important, Apple’s Lightning Connector isn’t a standard either, and it does just fine – well, until recently. What really matters is […]

UL Certification is a Band-Aid®

I recently got in an extended discussion with a UL Supremacist around this, after I said something was UL Certified when that wasn’t technically true, because UL is a Band-Aid®, and […]

California May Mandate Bidirectional EVSE

While I wouldn’t want to rely on a bidirectional EVSE as a complete home backup, it is a great solution for load shifting, and would be an excellent supplemental option when combined with a small permanent battery installation for home backup. As is the case with many of these things, California seems to be driving progress here, with the potential […]
