Re: automatically ajusting EVSE for off-grid/current sensing

48v at 410ah is a very impressive battery bank. Are you sure you don't want to go off grid?

I only have a little 24v 255ah warehouse tug battery for powering my water well setup.

I would like to, but I would need a LOT more solar (and not much more space) and a lot more batteries. Most of our useage is the geothermal heat pump that pulls 5 kw running :)
3 kw solar pv - XW6048 - eight L16's
4 ton GSHP - 1 ton ASHP
2003 VW TDI 200k miles - 52 mpg lifetime
EVSE level 2 - Clipper Creek HSC-40
2013 S model with QC package Mar of 2013
lost first bar @ 72k
@82k miles - 58.98Ahr - 90SOH - 87.70Hx - 256GID

The EVSE control box came in and opened it it up to find tie points on the board and documented where i got the signals. LED 2 did not have a test point, so i jumped on the current limiting resistor but it broke off, so i put in a through hole resistor to repair it, it was ugly, then i used black RTV to stick the wires to the board and that was mess too. I got a used j1772 handle and 20' cord off ebay and will connect it in to test it on the car. I don't have 240v at my soldering station, but i did have a 480/240 --> 120 .1KVA control transformer, I connected it backwards to power up the 240v only evse. if it works it works.

working on the code now, the flashing LEDs is a tricky angle i didn't expect, looks like i'll have to read the input twice, 1/2 second delayed, and see if its different between each reading. i'll put the code up once its done.
