There is a future for V2G/V2H - just a matter of time? As electrified vehicles increase to the 10's and 100's of millions, the energy storage capabilities is significant when compared to both the grid power and energy levels. Will GM (Bolt) allow their CCS protocols to be bi-directional...

Has anyone actually installed the Nissan V2G/V2H equipment in the US? For several years, it's been discussed, but seems still only been available in Japan (or Europe)? There is a company making a small V2H CHAdeMO unit - just not very seamless! Some random thoughts/considerations; -...

Some inverters (smart UPSs as an example) have "floating ground" on the outputs and will throw a "ground fault" error when switched to battery power (shows on my OpenEVSE's LCD screen). It will not charge my EV unless I disable the ground fault detection when running on solar/batteries. The...

I have the ability to connect my OpenEVSE CC at my "solar shed". As I have a dedicated pole transformer and since I've about maxed out my number of PV panels, I routinely see 255 VAC at the inverters - yes it can certainly vary depending upon your situation.

My 2012 Leaf is set up to direct solar charge (off-grid) with this setup: 1. OpenEVSE (OE) charge controller that accepts simple commands to adjust the amperes. 2 Arduino controller that sends these simple commands based on solar energy production. 3. Sensor monitors the amperes out of my...
