Thanks for posting this. It would be interesting to see this data processed in other ways (mean, etc).

Understood, I don't think I'll have an issue that! The tax man loves me...

I sounds like you're back to 95% now! :ROFLMAO:

As anyone installed the latest Megarevo firmware dated 05/11/2022 at this point? I still haven't heard what updates or improvements have been made. Given how long it took for it to roll out, I would've thought you guys would've jumped on this. Unless everyone is waiting for someone else to...

I'm assuming still no word on this (48V version of the MIN)?

The thread I linked earlier has a great discussion on paralleling multiple batteries and is certainly worth a read. Ultimately, EE and forum member Solarod came up with what's likely about the best balance you're going to get for a 5 pack battery. Note busbars would be required, but looks like...

Is this somewhat unique to this model/brand SCC, or can all SCC be set to power the inverter first, then battery power with excess?

They were on YT, I don't recall the channel(s). They were not recorded in English and not split-phase. I almost completely hit roadblocks with the Huaya. I even contacted the company which manufacturers them for Huaya, and received no response. It's almost like they don't want to sell these...

Looks like one hell of a bargain :ROFLMAO:

I can't say I've ever heard of anyone making one out of wood, but being flammable, I'm guessing it wouldn't be to code. Anyone know?

In a previous (now deleted) thread and earlier on this one, I seem to recall others mentioning from 25-40 watts, hence my surprise you were seeing 70W. If you happen to think about it as you're tinkering with your system, follow-up verification could be good data for others. It also seems some...

I use these smart plugs, great for monitoring too. Requires an internet connection though...

If I'm understanding this correctly, it looks like your wire sizes are limiting for the task at hand. The 6awg is only rated to 65a, the 2awg to 115a, 2/0 to 175a, and the 4/0 to 230a. Correct?

Looks pretty minor to me. I would see if they will offer a partial refund either way. If it tests okay, I'd use it.

Near as I can tell, GSL does not manufacture any inverters. This unit is a Megarevo, they are offering a 10k in LV... I want to say I seem to recall they were going to offer a 12k as well, but I'd have to go back and look at their earlier sell sheets to confirm.

Great news, glad to hear it! Any feel for changes in the new FW?

Can it be done without causing any issues, like it won't limit export to grid, it can't be done w/o DC panel input, etc.

How much benefit is there to doing this with new higher Ah batteries verses just building the 16s pack with a 2A active BMS and hooking it up to the SCC and letting it do its thing over time (however long that might take)?

Without looking at them in more detail, they look like a rebadged GW/MPP.

My thoughts exactly!

I saw this thread and thought of the discussion here. https://diysolarforum.com/threads/calculation-of-parallel-string-battery-currents.37937/

Ideally you want about ~12-14 psi consistent compression on the cell pack. Obviously the sides with the most surface area will 'give' the most. The most common and consistent way to keep that pressure is by loading the ends plates with springs. So while the cell pack is under pressure, it's...

In theory, I believe you could also splice in another set of CT"s, like the SUN limiter inverter guys are doing, then put a set on each panel, but the ideal way to do it is as outlined by the other guys.

I used the battery QR code app from Google Play and checked the mfg date on several of my cells I received from 18650batterystore.com. Looks like they were manufactured on two different dates about a month apart and were manufactured about a year before I received them in April 2022.

Without batteries you'll only be able to use that solar power for "x" hours per day. So if you're sizing for your total yearly use, you'll have a ton of excess power during those "x" hours and no way to store that energy and still be relying on grid for the (majority of the) remainder of the...

Seems to me raising one side would cause too much panel shading for part of the day, not to mention possibly cause unwanted lift issues in high winds.

Based on his usage image posted above, it looks like he started pulling grid power at around 4:30AM.

Same, although I did not send them money as the rep was not responsive answering any questions and didn't seem to want to play ball... But was ready to take payment! I didnt get any warm and fuzzy feelings about dealing with him/them so I contacted Luxpower... three times, and got no...

Interesting and relevant, but I do believe he's also discussing in general terms and assuming the use of a more traditional passive BMS. I might be wrong (I often am), but in my mine the end result should be similar if top balancing first or just hooking up a battery w/o top balancing and...

Just to be clear, polyiso foam board does burn and the fumes are not something you want to breathe. The isocyanurate chemical bonds (nasty stuff), which improve its fire resistance compared to other foams, breakdown around 390F. Initially it burns, then chars, which starts to resist further...

Any idea why that was closed? I have not been able to find a UL listing for any of their NA inverters.

Sounds like you're off on the right foot. And yes, they seem to be pretty reliable up to 75% output, near 100% output they tend to give up the ghost rapidly.

Correct. I thought I had read they were having some type of issues which had yet to be ironed out on the larger inverters. If Megarevo isn't releasing them, I have no faith that GSL has somehow solved the issue themselves and they're ready for prime time. Again, I'd proceed with caution and...

Speaking of future firmware updates, have they released the (significant) firmware update they said was coming last month, or have they still not released any public updates yet? I've found it odd they've been so unresponsive with updates up to this point given it's a newish product and it...

Mine were 3 and 4 of 2021.

Yes, a hybrid (or HP) hot water heater is already built to do exactly this. In fact, I would even hook it up inline between another and use it to preheat HW as well for additional benefit (also good for year round use). This would be far more efficient use of this energy all around IMO. If...

Sounds reasonable. Those panels appear to take MC4 connectors.

There's little doubt in my mind these are not automotive grade batteries, so the date was reasonable as I bought from their first shipment.

Ideally you want to balance at the top of the curve (say above 3.4V/cell). If you're balancing in the flat part of the curve, it will be very inaccurate and likely result in cells deviating much more when at the top (or even at the bottom).

I think you've already found where I bought my Eve 280's, but there are other reasonable sources listed in other threads as well.

To follow up, I contacted SA TS and received a prompt response: "Although not the most ideal, this will work. As you stated, the batteries will need to hit their ON% to accept AC coupled power which will typically be achieved from discharging over night. I would not worry about using loads just...

Consulting the electrician sounds like an excellent idea. ;)

I never thought of drying food, that's an interesting idea! Cooling, dehumidification, and heating DHW seem to be the most common energy dumps. Mining BTC can require faily significant initial capital expenditures, not to mention a learning curve to get there.

Battery State Of Charge.

Even at today's inflated prices, I suppose you could build a nice ~100kwh DIY battery bank for under $25k. If you're looking at paying $16k-$17k for two inverters, the additional $25k or less for a nice DIY 100kwh battery bank seems like a no brainer. Then again, I can't fathom needing 30kw...

Excellent, I'm glad I could assist! I've worked with the team at Gogreenman Solar and they've been great, hopefully you have a similar experience from this point on. Keep us posted on your adventure!

I'm not sure if this is along the lines of what you're asking for, but I've found it to be very helpful for system modeling decisions: https://pvwatts.nrel.gov/pvwatts.php

90W

I've looked at a lot of inverters and have also patiently waited for new products to be released and/or be shaken out. 9 plus months later, I'm still waiting or have found myself disappointed with certain key aspects of cheaper alternatives. In the end, I keep coming back to the SA products as...

Given the cells significantly expand and contract, and EVE tests cell failure with a rigid fixture, it seems crazy to me that folks are using completely rigid fixtures. To each their own I guess. EVE recommends compression for maximum longevity, and they basically give us the pressure...
