[2020-05-06 04:24:50] <guru3> The fan sensor sounds less prone to failure, and provides a decoupling point between your energy load and generator load if needed. Like in the case of a dead short maybe?
[2020-05-06 04:27:05] <guru3> This stuff, both the motor and AC power, is stuff I don't know a lot about. I'd worry about using the AC cycle to determine crankshaft position because power factor/capacitive load/inductive load type issues as well that might result in your sinewave becoming slightly offset due to feedback from appliances?
[2020-05-06 04:29:20] <guru3> The fan sensor, combined with a current sensor and voltage sensor gets you all of the same information to control engine speed without worrying about the exact AC system. You could also add in temperature sensors to further optimise fuel consumption. Add in a CO2/NO2 sensor at the exhaust as well for further feedback. And I just realised that I've more or less described an ECU.
[2020-05-06 04:29:58] <guru3> What can I say, those bits sound like a nice doable electronics project with my skillset while dodging a lot of scary high-voltage AC.
[2020-05-06 04:31:45] <guru3> The switch to DC to work with a battery and solar system feels like a sound idea. Batteries will want to charge at a constant load so you can run the engine more efficiently charging than directly powering devices.
[2020-05-06 04:32:32] <guru3> Ideally you'd have enough batteries in parallel to handle any spikes in load and never need to run the generator for anything other than charging.
[2020-05-06 04:32:59] <guru3> It also becomes a more scaleable system as I think you've suggested, adding in solar panels, more batteries, and more inverters, as needed.

[2020-05-06 19:45:19] <Lucifer_arma> basically, yeah.  The most basic fuel injection sensors needed are a throttle position sensor, intake air pressure and intake air temperature.  You can add an O2 sensor to the exhaust to tighten up the mixture a bit.
[2020-05-06 19:46:07] <Lucifer_arma> I found a project where someone designed their own MPPT system with an arduino because it was pennies on the dollar compared to buying one, and obviously more flexible
[2020-05-06 19:46:31] <Lucifer_arma> that gives me the ability to isolate each battery, which in turn means I don't have to worry too much about matching battery types.
[2020-05-06 19:47:24] <Lucifer_arma> What I'm saying is, I can use a car-starting battery, which is designed to deliver a huge amount of power in a short period of time (500-700 amps) to handle power surges from turning on appliances and build the rest of the system around simply running them
[2020-05-06 19:48:37] <Lucifer_arma> adding an actual power distribution module controlled by an arduino (or possibly a raspi, depending on what I need) with isolated batteries allows me to take batteries out of the power mix to charge them and put them back in when fully charged
[2020-05-06 19:49:14] <Lucifer_arma> what I have now is a simple circuit I picked up off amazon that monitors the battery voltage and cuts off the battery when it drops too low (adjustable) and turns it back on when it gets up to a certain level
[2020-05-06 19:49:49] <Lucifer_arma> I have diodes coming that'll allow me to ensure the flow of electricity happens exactly right, with charging power coming through a specific line and using power going through another
[2020-05-06 19:50:31] <Lucifer_arma> so the batteries I'm buying are 12VDC, of course, 33AH at 10 hours.
[2020-05-06 19:50:36] <Lucifer_arma> ]math calc 12 * 33
[2020-05-06 19:50:37] <ljrbot> Lucifer_arma: 396
[2020-05-06 19:51:09] <Lucifer_arma> so about 400W.  To reach the same power levels as the generator, I'd need 10 of them, obviously
[2020-05-06 19:51:28] <Lucifer_arma> that's for the max generator power level.  But then you need the power factor for the inverter, which is typically around .85
[2020-05-06 19:51:37] <Lucifer_arma> ]math calc 396 * .85
[2020-05-06 19:51:38] <ljrbot> Lucifer_arma: 336.6
[2020-05-06 19:51:50] <Lucifer_arma> probably better to round that down to 325 watts
[2020-05-06 19:51:56] <Lucifer_arma> ]math calc 4000/325
[2020-05-06 19:51:57] <ljrbot> Lucifer_arma: 12.3076923077
[2020-05-06 19:52:01] <Lucifer_arma> so about 12 batteries
[2020-05-06 19:52:28] <Lucifer_arma> There's room for a shitload of batteries, more than 12, in the battery bay.
[2020-05-06 19:52:34] <Lucifer_arma> so this is doable, right?  ;)
[2020-05-06 19:53:33] <Lucifer_arma> also, it's worth pointing out that I've spent a lot of time as an automotive technician, so the engine parts of the project are absolutely no problem for me.  It's the electrical stuff that I'm having to learn brand new.
