I have been searching for a while, wondering why string/hybrid inverters (any inverter that DC couples PV panels into MPPTs) don’t offer the capability of direct DC charging of EVs. Heck, they can send DC current to integrated (or closely coupled, or even non-closely coupled) residential battery ESSs; be they low voltage (~48V) or high voltage (I’ve seen up to 600V). And EVs can accept “DC fast charging”. I thought maybe there was some limitation in the EV charging schema that I was missing.
Then a few months ago I found the dcbel 16 that was mentioned earlier in this thread (I didn’t find this thread until a few days ago). “Huh”, says I, “I guess it is possible”. But this solution requires that you use their inverter. I was hoping to find a solution where I could add an EV charger to an inverter that I had in mind (say, something like the Sol-Ark 12K or 15K, or maybe an Outback).
Then I discovered a company called Enteligent. they have some pretty cool DC optimizer/RSD devices that are either available now or are imminent, but they also have just what I described above and more: an EV charger that connects to an inverter, which takes DC current from your PV panels and sends it to their EV charger, which sends it to your EV (without first inverting it to AC). It “can also be powered simultaneously by the AC grid” and battery ESS so that it “is up to three times faster than AC Level 2 EV chargers and delivers at a fraction of the cost of dedicated DC chargers”. It is also bidirectional, so you can use your (appropriately equipped) EV as a battery ESS. It is “Coming Fall 2022”. They are working with several inverter manufacturers (including Sol-Ark). I spoke with Ed Rosenberry. Nice guy. Very helpful. This piece of kit looks really promising. You should check them out.
