@Cmiller — you said you’re successfully AC coupling off-grid with XW Pro? I’m having major power quality issues with a Sunny Boy (XW Pro in backup mode), and will eventually start my own thread. But for right now, I just wonder which GT inverter you’re using?

I was referring to this statement: @AntronX seemed to float the idea of hacking the ECU via CAN to get a sustained 16kW output. But if the Toyota guys implemented a time limit on the forced charge like you described, then I don’t think I’d even want to attempt to seek that kind of continuous...

Based on behavior I’ve seen, the voltage and current limit isn’t stored in non volatile memory. If CAN comms is lost, or power cycled, it reverts to default voltage, which must be written to nonvolatile memory. At $50/unit, seems worth a gamble to experiment. I’d sure like to know how this...

It’s a 2012 Prius V.

FWIW, I’ve already got CAN control working on the Flatpack2, able to set voltage, current, and default voltage. Using ESPHome, and the code for multiple units needs to be modularized, but I’ve got it working with two units. If I can really feed up to 400VDC into these things and use them as...

Appreciate your sharing of knowledge! I'd love to know exactly how much worse the efficiency is, but taking into consideration the benefits and versatility, it's hard for me to imagine a standalone generator being superior for rare/occasional use. It'll be one less piece of equipment to own and...

Bummer. I'd prefer if my tap/mod was only hot when the car's ignition is on. This gives me confidence that I'm not likely to overburden or wear out any of its components with a few hours at 2000W or less. (y)

I can't even believe I'm typing this right now... I installed a grid-tied Sunny Boy PV system on my in-laws' garage roof, and it's been running perfectly for nearly two years. Recently, the red light on the inverter came on indicating an error: failure in string C. Not coincidentally, the...

Yikes. Curious to know what voltage that was... @GXMnow shared a similar story in another thread not too long ago, in response to @SeaGal 's assertion that 48V may be safer than 12V, given the lower amps per unit of power (which I tend to agree with, on its face). Seems sweaty arms are something...

I've already got a pair of XW Pros on the wall, and 48V battery attached to them--and these high-efficiency telecom 48V rectifiers on hand, paid $50 each. If I smoke one, it's not a major loss. Not really sure why I would want to spend another $2000+, unless it's to have some extra redundancy on...

It's a DC Solar trailer. I filled the 100 gallon tank with off-road (dyed) diesel in summer. Added a preservative later, but not sure if it mixed well. Meanwhile, a close family member manages a fleet of commercial trucks, and had major issues with gelled fuel during that "polar vortex" event...

I recently picked up an old, used Prius. Planning to use it for transport, and hope to fall back on it as a generator, should the need arise. I've read plenty of threads about using the Prius 12V system to drive an inverter, and the inverter to drive a battery charger, but I'm seriously...

I got a phone call from co-op asking if I had solar, since my usage had basically gone down to zero. I confessed I did, but explained that the system was isolated from the grid, connected like a backup generator. Guy from the co-op said that's fine, but I couldn't connect an inverter to the grid...

Yep, exactly. My local co-op has raised their "availability charge" by nearly 100% in just 2 years, while dropping per kWh rates. They've also had ads in their "free" monthly magazine urging members to contact their politicians about unfair net metering. (aside: I do agree that net metering is...

I'm interested in this, as well--I've got 16x 100ah 12V nominal LFP batteries. They were on a 12V Victron split phase, but I've since moved to a 48V inverter, so now they're in 4S4P. I added an active balancer on each 4S string. The cost is significantly lower than, for example, EG4 server rack...
