So a while ago I'm just minding my business looking at cat videos on youtube and I stumble across a Will Prowse video. 4 months later I have this in my basement!!! - Thanks for your inspiration Will. I watched your videos and said - Hey I can do that!. After a lot of watching and reading I...

I finally got around to testing my system running 240 split phase. (my pool pump) It wouldn't start when I flipped it on - then 1-2 minutes later the pump would spin up and run for a while and then stop after a couple of minutes, then spin up again and stop. Something was not right. To recap...

Some interesting info to share. The past few weeks I've been having one of my two inverters faulting with an 06 error. Output voltage is too high. I've been working with Ian and MPP solar to troubleshoot. When Ian looked at my settings he had me change a few things as he had seen this...

Having watched all three of Wills videos on this and the responses from RUIXI I have to call BS . They said they were "sorry" about this that and the other thing? What company does that? They're going revert back to their old BMS and manufacturing methods because a DIY Youtuber called Will...

What Erik Said. The induction load wanted to pull from grid for support. It was looking for Split phase from the grid to power that load. There was only one circuit attached. Per Hedges post it would be nice to be able to tell it to pull from my Lifepo4's instead as it seems they can...

Bump. Back on sale until 9/13

I'm in Mass. Just putting together my small system now...So I'll let you know! Bottom line is it depends what you're trying to do. Dave Poz (YouTuber) is also in Mass. He does a lot of solar projects lastly the Alt-E store is in Boxboro and Amy is on this forum so you have a great local DIY...

This is what I see. I have 2 hybrid units. Each with 1300 watts of solar 2s2p strings 325 watt panels. Open circuit voltage of 40 volts each panel. The strings themselves measure 75 volts at the combiner box. The voltage via the mppt fluctuates from 55 to 72 depending on wattage being produced...

Thanks again Bob142 for the heads up on these - I was considering a DIY setup but the sale price on these brought them down to at or below a DIY price. They appear to be well built with a solid BMS and warranty from a US company. I'm not concerned with the 90 vs 100ah issue and how they were...

"scheduled the pickup between 9AM-and 4PM" I wouldn't call that scheduling a pickup.. More like wait around all day and see if they show

I have similar specs as yours but with 8 panels. (VOC of about 38) I chose 2s4P. I'm in New England so that gives me lots of buffer on variable temps as well as better shade production with 4 strings. In actual use, what I'm seeing at the inverter is a VOC with no sun of about 71-75 volts and...

Second this. The reliance pro-tran series are VERY easy to wire to circuits in your panel. They have some YouTube videos demonstrating how. You could buy a 6 circuit version and have all 6 circuits powered by solar, grid or a combination. You decide based on switch position

Was this confirmed as a a solution? Using the alt e store's wiring table for inverters My hybrid mpp unit at 2400kw should really be wired with at least 2/0 cable. I'd like to go to 4/0 for good measure on both batteries and inverter connection. I'm perplexed as to why the inverter manual calls...

The 1.56 accounts for both over irradiance and 3 hrs continuous use over normal expected use. I'd suggest everyone watch Amy's video on wiring your systems to ensure proper sizing of wiring fuses and breakers. The explanation for the 1.56 starts at about 9 minutes in.

Corona virus delays. Cancel the order and buy it from Ian Roux at mpp solar USA https://usa-mpp-solar.com/home Or his eBay store. https://www.ebay.com/itm/254515820464 These are stocked in the US and warranty is via Utah not China .

Except that went all over the place discussing disparate cells within packs. You can parallel connect two complete but differently sized batteries. They will keep the overall voltage equal and current share between them, with the larger battery providing more for the loads. Those 272s and...

His beef was with the terminals. They have small screws and he has concerns about durability. At just $100 less than Battleborn MSRP he's suggesting to take the Battleborn. At Costco these are $300 less so it's no contest. To be honest I fail to see how Battleborn still charges a grand for a...

Sounds like you fried your solar charger controller. Both the the pv and batteries connect to it. Easy board swap. Literally 20 minutes. Have you confirmed your inverter is fine by running loads via shore power through it? As a poster above said there are fuses in the system that you should...

If you're only looking to power a few circuits and want the flexibility to switch circuits on and off while feeding solar use a Reliance 6 port Pro-Tran switch. They have double throw switches allowing you to feed the circuits via grid or solar at any time. They are a breeze to wire to your...

I'd think affording yourself the opportunity add larger gauge cables would be beneficial. They have a video showing that the 14" 8GA cables have the same loss as 7" 10 GA cables. (3 watts or so) I was planning on 8GA cables for a 24volt 8S with 24" cables. I'm thinking that may be more data...

James - Thanks for the call and the follow-up on the forum explaining things. It's precisely that kind of customer service that breeds repeat business - Myself included

I've found that some things propagate and some don't I don't recall exactly which so I realize my comment is of little value :)

Exactly I'd spend the money on. Better made one like. Blue sea 187 200amp breaker. Its 80 bucks https://www.bluesea.com/products/7149/187-Series_Circuit_Breaker_-_Surface_Mount_200A

I think you're referring to the Growatt Models - Internals are the same as MPP - Clearer manuals and they already include the Parallel boards. These are sold by Ian Roux via in Utah as well

You have a couple of places you need to set the cutoff voltage - Setting 19 (low DC cutoff) and 21 - Battery stop discharging when grid is available. 21 assumes your connected to Grid for ac charging and supplemental power. If yes then set these both to the same setting (or as close as...

I just ran a ground to the internal (lower right) mounting screw
