Wow, you're a lucky man. That's the sort of thing I do, but not always lucky. :)

I can't see how they are attached to the I-beams ... I assume they were otherwise they should be in the next state by now. 😁

That's very surprising to see something as detailed as they have provided. Only thing missing is an actual circuit diagram. Certainly very helpful for anyone working on that particular inverter. Unless I've missed it, you still haven't said what brand and what model your inverters are. A link...

Haha, thanks very much. Thanks :) The inverter design is by Warpspeed who's here on this forum. There's a thread all about the concept here. I built the inverter and wound the transformers etc over the last three years with lots of guidance from Warpspeed. There's some threads about it over...

Here’s some of the things I wanted in an inverter and you guys have mentioned a number of them as well. The idea of having all the switch gear inside the inverter was attractive to keep it simple and neat … and avoid lots of interconnected boxes on the wall ... and the bare minimum of...

I have read all that I can find ... but none of it mentions the parameters that I saw online while connected to the history of the actual inverter I bought. That's where I saw the 253V maximum figure. Wish I'd at least screenshot all the settings. Frustratingly I can no longer even find the...

Yes. Agreed Haha, very good question. Definitely, me too. Yeah ... so how do I find out? Ask someone who knows? Where do I find such a person? Read all the setup data and somehow interpret that? What if I simply wind the Warpverter output up to 253 and see what happens? Am I game? 😁

Thinking about it ... the only time I've seen the AC-out over 241.5 has been when the Growatt is pushing heaps of current back through the Warpverter ... and as I mentioned above, presently the Growatt is set to limit the output if the AC gets to 253V. I saw it get to about 246v on the...

Warpspeed's already answered some of this and can explain better than I can ... but yes, directly into the AC-out of the Warpverter. Yes, the loads were often up to 6 or 7kW over and above the 5kW the Growatt is contributing ... although first thing in the morning there's not much load on...

Hi, there haven’t been any comments here lately so I thought I’d update some details on my Warpverter installation. I mentioned a while ago that on good solar production days I was running 6kW of underfloor heating for hours every day After a only a few days of this I realised that it really...

Thanks for the explanation. I shall mull it over for a while.

I never knew they made such a thing. I have a couple of Kilovac solenoids to isolate gear in my system ... though may be overkill in this situation. 12-900V contact rating and 500A switching ... and 48-72V coil with economiser to reduce hold in current. The contacts are in a sealed...

Hang on ... so at your house you have your new HPHW feeding into your original propane hot water tank? ... which is just used for additional storage? ... or gas heats that to keep it up to temp? Yeah we do have a filter in the kitchen.

Thanks for pointing that out. Encouraging. And no, I'm definitely not worried about bugs in the water being fed in to the cold side ... it's the same water we drink and use in the house from the rainwater tanks ... and have been for years. I am inclined to agree. I know lots of people are...

Looks like a very handy device. So is there any reason I can't fit a preheat water tank set to 60C (for safety from Legionaires) ... and fit one of the mixing valves on the outlet set to reduce to say 35C ... a few degrees below the lowest expected outlet temperature ... then let the gas...
