Personally, I wear a belt and suspenders with my parachute when I jump out of an airplane! 🙃

DOn't all mowers have a seat switch on them from the factory? My EGO 52" sure does.....

I'm going to ask a really dumb question.... why not add a switch under the seat that connects a precharge resistor? By the time you are seated and squared away, the caps are precharged and you turn the mower on as normal??

An observation of how a proper shore power generator ATS works.

I have an RV transfer autoswtich and when in shorepower, the neutral ground bond is broken on a 2nd set of contacts. On generator power the neutral and ground are bonded in the switch.

Hey I just read your oringial post again... those growatt inverters are not for the US market. They have a ground neutral bond on one end, not correct for split phase. I think there's a screw in the chassis that needs to be removed. Check will prowse youtube for that screw. It was all the...

Where is neutral to ground bond? When you say autoformer , it's job is to nudge the neutral around so it stays centered between the two 120v hots. If you had only a small load on one leg and a heavy load on the other 120v leg (unblanced), then the autoformer would be moving the neutral around...

Was there ever a solution or resolution to this?

One of my neighbors has a 9kw system and his min power bill is $9.36.... I have a 16.5kw system (ie >10kw) and they charge me a demand fee for the reverse power going out. My min bill is $14 and change. Please note my numbers are a little old because I haven't checked his bill lately... so...

That unit is a rebranded clipper creek and it needs a ground. It'll run a self test before working..... are you using it as 120v or 240v, by the way? You can easily feed it with 240v..... unfortunately you cannot set the charge current except to 8 or 12 amps. Other EVSEs like OpenEVSE allow...

Are you using the original EVSE? does it indicate a ground fault?

I ran into this problem testing the RSD modules... no setting on my Suny island would wake up the tigo modules. Later someone (maybe you??) suggested there was a min number of panels to get things kicked off. the 5v on the input makes sense now.... I would have had to put 9 panels in my test...

I've not been impressed with RPI.... I tried hosting Home Assistant on one and it kept not booting. If the OP needs a microprocessor based solution, I would use a ESP8266 or ESP32. but I think what he wants can be done with simple 24vac relays.

YOu can interlock the thermostats? it's low power, so small relays could be used. I imagine you would have a priority order so that if the main house called for heat, the bedroom would be shut off. I would do it with 24vac DPDT relays. Run the common for the thermostat thru the contacts of...

I'm using sunny boys AC coupled to my Sunny Island and want to feed in from a generator also. My generator is an onan RS12000 that has a microprocessor based speed control so it does not idle up to 62hz. This presents a problem that the sunny boys may backfeed the generator. I need an...
