Yea I figure a small generator with a charge-verter run would be less costly. I've got an old 50cc two stroke mitey-mite that's loud as hell but more than enough to cover my loads if run for awhile....has a 24v dc output for my battery pack. Yes currently just 24v stuff. My daily average usage is only 3.5kwh and that's with the occasional 12-15kwh day if we have guests in the all electric (heater) guest room.

I use way more electricity now than I did when I had the grid. The base loads would be a chest freezer, refrigerator a few fans; in the winter the coal stove uses ~7KWh/day, 90% of these being a large convection fan I added. I have plans to upgrade it to something more efficient get next season. 12k BTU minisplit would be the next biggest load followed by cooking.
My AIO idles at 100W too..

When I find land to build on and sell this house I will have no grid connection.

whats your actual $/kw cost.

It's somewhere around $0.15 kw/h

just curious why you seem to be adding so much. decent roi

Part of it, I use more now than I did before solar and battery. I also plan to get an EUV in the very near future and add more minsplits. It's also became a bit of an addiction, I already have the panels and mounting and I'm getting a great deal on cells (I hope).

or just pure hatred of the power company?

Not really, know quite a few people that work for them.
It's more that I've lost trust in the reliability. To many times I'd come home from work to a cold house because the stove went out while I was at work, the noise of the generator and getting it hooked up in shitty weather.. The final straw was the time it went out frying some bacon and cooking omelets, luckily my propane grill was on the deck outside the kitchen...

It's mainly piece of mind, one less thing to worry about.
And yea, part of it is giving the finger to the power company.
 
My great grandfather till the day he died swore eventually electricity would be too cheap to meter. I feel sorta bad. They converted their whole house to electric. Except their forced air furnace from the early 80s which they never used. Fire place and electric radiative wall heaters throughout heated their home. It was pretty cool, but he had the mindset it would all be done with nuclear. Apparently that was the idea back then.

My mindset is an energy efficient small household. Luckily I'm in a mild climate. That being said, the poor guy was right eventually, but it would be solar that makes it too cheap meter.

My next build will extremely efficient. I'm hoping for ~7kwh per day in the winter and ~4 in the summer.

Yea that's downright efficient for the average home. Depending on new regs and codes, Solar may eventually get so cheap that it may be cheaper and easier to just diy solar rather than have costly and labor intensive upgrades to all these old homes. The high labor costs and material cost here (home efficiency upgrades) are making it very expensive, and if one can diy solar than it's pretty much a break even sort of thing, efficient window installs are fairly easy and can be done one at a time. most of the houses our neighborhood will NEVER be put up to code as far as modern insulation R value for this climate and it is not high like in PA.

Excellent point.
Maybe I'll just keep buying batteries and panels 😂

We have a dozen people in the neighborhood with grid tied solar installed on their homes with no sheathing (paper/wire/stucco only) and zero insulation in the walls. Oddly enough the few neighbors that have filled their walls with insulation and added extra in their attics havent seen the need for an expensive grid tied solar install here due to wildly high labor and upcharge costs.

In the winter I was worried about keeping the batteries warm, now I'm worrying about keeping the inverter cool. (battery temp is F, inverter is C).

I've been running an oil filled radiator in the basement the past few days since I unplugged the stoker stove for the season.
No real updates. Everything is performing flawlessly.
Just bored at work wishing I were home to fight the power of the sun...

So I can fit 2 of the ASPs on the wall behind the drill press. I'd likely also add a 100 amp sub panel that is fed from them, then feed that back to the main panel.
Underneath all that will be the next battery rack, it's an interior wall so it will be much easier to keep them warm in the winter.

I don't have enough room on the exterior wall to mount 2 ASPs. I'm thinking I should hang everything on some strut, making it much easier to yank everything when I move.
It would also force me to clean up organize a little bit. 😂


4.4MWh on the ASF.
Why can't we have graphs like this year round...
Happy Friday!

wonder why the grid was used. batteries should've been able to cover this load

I'm pretty sure that's an MPP / Voltronic.

Yeah from the image and descriptions it is identicle. Always a problem with these companies that throw their own label on a product knowing who the OEM is. Especially since they seem to mix and match every few months.

However I am reluctant to say that is a Voltronic as I could get scolded. :p

Try disabling it. I suspect there is a spike solar assistant isn't catching causing the inverter to bypass to grid. I had the same issue with my tp6048 after I first commissioned it when the well pump would cycle; disabling bypass on overload solved the problem.
You could also turn off the grid breaker.
As long as you have enough battery to keep the BMSs happy, I'm confident the SRNE will handle the surge.

Not worried. If it felt like switching over that's fine with me. Just curious is all.

In other news my fully solar powered space is now occupied and it is shocking how much power is needed with all utilities being electric. No idea how the fully off grid people are able to do it
 
Q. Would ASF48100U200-H share the load with grid and battery in case of overload?
If the load increases to say 12k will it get the extra 2k power from the grid and supply almost 10k from the battery?
Reason I am asking is I plan to use this mostly from solar and grid will be just a backup and some battery charging instances overnight at about 20A max and that is why I was thinking of using 8/3 (I have a piece that will work) for inverter input and 6/3 for inverter output. Is this configuration ok?

No, it will bypass to utility. It' can't blend the power.
I would not use the 8 AWG for the input.

I ended up using 6awg on AC in/out, but honestly looking at the wires coming off the top of the connectors, I am pretty sure SRNE did not use 6wg internally. I just flipped the power on, so now I have to try to figure out how to use it :p Any secrets to hooking up Solar Assistant?

I didn't check them but appeared to be at least 8AWG and silicone coated. I'll see if I can see any size on them.

Make sure your own the latest stable or beta, plug a USB B cable into the inverter and the USB A end into the pi, select SRNE for the inverter type in SA configuration settings, enjoy.
