Bad days for Solar Production.

Didn't know where else to brag - but I'm so excited - I have generated MORE PV input than consumption in about two months - in the winter!
We only had 6 (out of 32) panels hooked up with no batteries for a few weeks. Today, we surpassed consumption with production. A banner day to me.
Now, back to the rest of my projects...

I think most are just using regular round heating duct found just about anywhere.
Yea I know, I mean how I'd personally organize my pipes and which rooms and where during which seasons.. I have green house that produces heat in winter and going to dig geothermal and other stuff so something for me to ponder.
Maybe you know.. I have a lot of questions I might call rheem
Why are these hybrid heat pumps all 240v but the straight heat pump water heaters are all 120v?
Do the 240v hybrid heat pumps use 240v for the heat pump part too or only the electric resistive heaters?
Why are the non hybrids more money if they're just the heat pump part...?

If you are going geothermal then I would look into heating your water with the geothermal heat pump. More efficient.
4500W heating element so 18A per leg.
Uses 240V for compressor, about 150W per leg, I just checked.
Good question, don't know. I looked at compressor size and did not see any difference. I would not buy a heat pump only unit. There are times when the heating element can work well as a dump load or quicker recovery. End of the day battery bank hits full charge and heat pump water heater is not 100% full of hot water. Just switch over to the heating element to dump excess PV.
It is more efficient sometimes. I can just blow in ground heat into the inputs of all of the stuff when it's colder out but when it's warmer out it isn't more efficient (for the water heater) .. but it is for AC units as ground here is 49 degrees at 8ft (pretty average for the global temp that low)
Yea but they should make the non-hybrid 240v too so it balances on my solar
wow... so the real option is to get hybrid for solar and just set it to only use heat pump lmao wtf
they don't even have ONE option that is heat pump only and 240v
It must be marketing.. wtf I just emailed them asking why
usually in my experience anything that is "hybrid" and does "multiple things" is more expensive than 1 single thing that is simple.. but then if you buy a bunch of single things to do what the hybrid does then they're overall more expensive.. tools for example
these heat pump water heaters are very weird prices.
& yea the dump load is good. I got a hot tub for that but can prob put some lines on the hot water heater and have a heat pump hot tub lool to throw all that heat into the air.. maybe not a great idea
but yea it seems the 240v is the way to go, worst case I can throw some elements on it that are like 1500 watts instead of 4500 and as far as I see no water heater runs both elements at the same time so 1500 is a bit nicer than 4500 for my system. rheem seems to have tons of elements to select from
thanks for the info on the 240v compressor that really makes the purchase easy

Great month of March, 7288 kwh for the month, new one day best of 402 kwh.

What's in a title?
Yea, it's like a terrible April fools joke here too.
Had to exercise the generator because I'm to stubborn to use the grid

I thought maybe you would get more snow and clouds today than we received. Looks like you had a good day like I did here. Nothing spectacular but OK.
Only excess load I have been running since last Friday has been running the hybrid heat pump water heater during the day. Just enough sun to hold battery at the SOC in the morning, power loads during the day and make hot water.

Not bad today, 27Kwh from the 8.4Kw of panels. Everyday since last Thursday has been net negative overnight and slowly dropping battery SOC. It was somewhere around 50% SOC this morning.

400KWH/day is a stunning amount to actually collect. Where on earth are you using it? With minimal A/C and Heating thru march, I maxed out a day just under 100KWH, but I'm flatlined at 100% charge pretty much every day just after noon. Total battery charge dipped below 20% a couple of times.

I truly don’t know what I’m capable of at this point.
My batteries are usually charged by noon and then they just idle with the house usage.
Today I got 60 kWh but stopped charging at 12:30.

2 ev cars, bitcoin mining, in floor heat in shop, heating my basement, heating my house, and charging battery from over night ev charges, or bitcoin mining all night long if I know there will be sun the next day. All manual loads turned on by wifi switches.

Need to wire in some loads to use that power up! As soon as it warms up, I will be wasting power with not enough load. Might buy a few more cheap old bitcoin miners, but they cost money too.

Passed my inspection two weeks ago, got my sell back meter on Monday; now 5 days of no sun in eastern Iowa. Murphys law sucks. Plan to add some vertical solar to boost production on crappy days. Wonder how refection off the 1/3 acre pond will work with vertical solar?

Lost a few hundred watts didn't realize I was topped off, threw the oil filled radiator on for a 920W load.

Catch, make or grow everything you can.
December was crappy no doubt about it.
Since middle of Feb has been Fantastic!
now we just coast all the way to October. then crappy will return no doubt!

Record for me today and should get better next week, also got another 5kWh of batteries on the way.

one step at a time. eventually ya get there.5KWH here, 5KWH there pretty soon you'll be talking about some real battery capacity.
10kWh of battery is a good size for a system collecting 6kWh per day.

I have two jk BMS to build a couple big 48V batteries but keep finding 24V100Ah or 48V 50Ah for $350-$400 which make it marginal versus diy cost. Not sure what the end goal is but I suspect the answer will always be "more".5KWH here, 5KWH there pretty soon you'll be talking about some real battery capacity.
