Big drop in September. When did you get the panels, in August as well? Must have, or you just disabled half the house's circuits.

I added panels clear up to January...which was when I switched all transfer circuits on...about half of circuits...but the major ones. That damn Mr. Coffee...switched in January too!

Here is my kWh per month history, since 11/2021. On 12/1/2021, someone moved into an empty house on my property. (Not a squatter; a legitimate tenant who pays rent.) The bill has never been the same again. This party requires a room temperature of 80F which implies heating on 360 days of the year. That house has a dedicated propane tank which the tenant pays to get filled.. but free electric heating is better.. for *them*. They use about 600kWh a month according to my later installed sub meter.
I have:
* since 2004: a 5kpv grid tied installation which explains the lower summer months
* since ~3/2023 a 3kpv offgrid car charger
* since 1/2024, a 6kpv offgrid setup for the main house
First 2 months of 2023 vs 2024 show 800kWh savings, presumably from the 2 new systems.
(Remember us wealthy Californians enjoy paying 60c/kWh. To cure that wealth problem.)
My idea is to have 2 more separate off-grid installations for the 2 detached houses.

I had not paid much attention to the BMS status lately, mostly because of the clouds, the SOC never made it past 90%. However, today we got good sunshine and.. All 5 BMS report "Full" (no runners causing OVP)
I have full BMS communications enabled.

Don'tcha know the whole purpose of my 4.4 Kw of panels and 25.5 Kwh battery bank is to assure I get my coffee first thing in the morning.

Gettin' down to the Dregs of the Mr. Coffee this morning after two days of virtually no sun. Gonna let it run and see what happens. Not sure if it will make it to sunrise or not. This is a test, this is only a test....

Had enough sun to take my batteries from 7% SOC to 80% SOC... woohoo!

He will need a hot tub to burn all that pv. Cheaper than an EV.

Looks like Sungold has a new inverter listed:
https://sungoldpower.com/products/10kw-hybrid-inverter-48v-split-phase
Is this a Deye 10k rebrand? @42OhmsPA So this is a poor man’s SolArk basically?

It has 4 mppts, max 13kpv.. but only 10kW output
Not worth the $2400 price IMO
Unless it can be operated parallel for higher kW
I don't see that though
Edit: parallel IS supported
They seem to have two units that are 10 KW split phase 48 VDC hybrid inverters.
The unit above is SG10KHB-48 and priced at $2400.
10KW Hybrid Inverter 48V Split Phase
Highlight: ★ Hybrid Split Phase Inverter: 10KW Pure sine Wave Inverter 48V DC to AC 120V/240V, built in 4 MPPT Max 500VDC input each total Max 13000W PV input. ★ Multiple Charging Modes: Off Grid Solar Inverter have 4 charging modes: Only Solar, Mains First, Solar First and Mains & Solar hybrid...

Another unit is SPH10K48SP and priced at $1670.

The price difference seems large for what appear to be minor differences in specs.
SG has 4 MPPT and 15 KW PV, SPH has 2 MPPT and 11 KW.
Other than that, I can't really see anything significantly different. What am I missing?
The SG unit says cooling is convection, but it clearly has fans depicted in the user manual. UL 1741 isn't listed either.

Yea. I posted it in an old thread of yours about senergy. I really thought it was that one
Then I downloaded the manual and compared with Senergy, mpp, and megarevo and it’s definitely the megarevo.
So they went that route and powmr went the mpp route. I guess we will see how it pans out
Imo the SRNE rebrand (the cheaper one) is still the benchmark. It has ONE shortcoming, but I’d rather 2 sub panels than equipment that doesn’t function but is stackable.
They (Megarevo and mpp) probably stack nicely in the trash too.

Thanks for looking into this @G00SE that makes sense. I know a lot of the guys in Europe and Africa love these Deye 10k, but they’re hard to get into the USA.Yea. I posted it in an old thread of yours about senergy. I really thought it was that one

It does look also like a Megarevo
I’m not sure what factories are spitting these out. I’ve watched some Deye main board replacement videos on YouTube and I know the boards are harder to get down into and they usually have a heat sink on the backs of the power boards on the low sides. I know I’ve seen alot of posts of guys who love this build design, but I also remember the Megarevo drama so… something to watch I guess.
My SG 10k has been running wonderfully I can’t complain, do wish I could parallel another one tho
There’s a couple of people in here that seem to flip the deye stuff from time to time.
You can find the 12k version (9k output) for around 2500 on eBay.
Seems like a fair deal to be honest if one is interested in that route.

100% my sentiment!
2nd best choice is a second unit on its own battery bank with full communications, right?

Probably the same as the new inverter Watts247 is selling.
Maybe the issues are fixed but I'm not into experimentation when it comes to inverters..........

I think SRNE has April release for stacked 10Kw units. That could be a huge game changer.Yea. I posted it in an old thread of yours about senergy. I really thought it was that one
