Will likely work as you've described. If you can add a tempering valve to the hot water outlet then you could safely "overheat" the tank water, and the mixing valve would bring it back down to 120F or whatever you set it to for use. Effectively makes your hot water tank bigger. If you decided...

I think your concerns are valid. When deciding whether to put panels on my 5:12 pitch roof (~23deg) or a ground mount, I paid attention to how long after a storm the snow remained up there. After a fairly big storm (~1m of snow) it took about 10 days to clear, and about 3 days after a 24cm snow...

Hi Badbyte. congrats on getting the unit. Just curious if they go into the UL1741 cert in any more detail. Like is it SA or SB, etc.

Pulse could come in via the ground wire. And even with a switch/CB off, a lightning spike could jump the gap in the device; that is less likely if you have various over voltage protection devices but in theory possible.

Just read an article that the US administration announce a 4 fold increase in import tariffs on various Chinese goods, including EVs, Solar and Batteries. Have not verified this report yet, but if true will likely raise the price of much of what we do here...

It would be nice, as well as opening up a wider potential customer base, if your batteries carried a general UL9450 certificate. There are a few other batteries which do, and as more and more localities are requiring UL9540, they are poised to picking up that market. EG4 could tap into that if...

Very much agree with Robin on this. 200A passthru to your main panel is not a good setup for real life long outages. Not only for the code requirements Robin mentions, but the hard reality of an extended grid outage brings in new problems which many who choose this route have not considered. If...

You might want to consider just using non-rechargeable Li batts. That is what I do in my weather station (also an Ambient Weather model with a small PV cell built in). Still on my first set of Li AA batteries going on 3 years. They probably won't last as long if you don't have PV helping out...

The answer is maybe, but probably not (sorry can't be more definitive). The issue is many/most on-demand/instantaneous water heaters are not designed to take pre-heated water as input. They expect cold water in and run their burners full all the time water is flowing thru them, assuming it is...

That $6200 price is about $1k more than the one other place which is taking pre-orders for it (TheSolarBiz). Still will be interesting to see what the official pricing is when Midnite finally releases it.

Have the same inverter. I did have that 35A breaker pop once; took me a while to find it. But in my case I think it was valid in that I had a bunch of freezers on it, which were all off for a while due to clouds and a grid power outage, and then they all came on at once. But in researching...

Yeah. I contacted the seller and got the same info. That is a really good price. Unfortunately for me, no UL certs.

Sounds good, unless that 200AH is for the pair of them together. In which case it is closer to the going rate...

Hard for anyone to answer your question without more details. The proper size of the concrete post will depend upon the wind and snow loads on the panels, and your soil type (e.g. how much force the soil can take). It is NOT just make a pier that goes down to below frost line the minimum size of...

We live in a culture which promotes buy the latest and greatest, whether you need it or not. I suppose it keeps consumption high, but really does not serve most consumers all that well (IMO)... My general rule is use something until it breaks or no longer will do what you want from it. Planning...
