Hey everyone, Sorry for delayed response! So two items: 1) Initial problem - I had to cut and resolder the wires between the ecu and control unit/screen. The problem was with my soldering.... There was a break in the connection. 2) Afterburner. This unit is awesome and more importantly the guy...

All good points! I too have read the manual and no signs of a 19 fault or error code. The power switch is on. For me, the screen turns on only when battery power is applied (regardless of whether the power switch is on or not). It does not power up if only PV or AC is connected... I think it's...

Hello everyone, I have a SPF 3000TL LVM. It was working beautifully over the summer, but shut everything down as we got into colder temps because my DIY 24V LifePo4 battery was not insulated or heated. I've now rebuilt the battery bank in a heated box. Once it was hooked back up to the...

Hoping to have it installed this coming weekend

Thank you for the responses. I've actually ordered a afterburner which will replace the controller and ECU. Haven't isntalled yet, but excited!

Help?

Hello forum! I've got a 8S/24V battery setup of 280AH LIFEPO4 cells. I bought and installed a SouthROL BMS. To be honest, I thought I bought a Daly BMS, but didn't realize until after it showed up, it's actually a SouthROL. It looks to be very similar to the Daly. The setup was/has been...

Hello everyone! I posted some threads late last year and everyone was extremely helpful! I return, looking for chinese diesel heater wisdom. Last year, I converted my shed into an office. I installed a chinese diesel heater in the attic, which worked very well with heating the space...

Thanks for everyone's suggestions to contact Amy Zheng... I've done so and waiting for her response. I have been dealing with some suppliers directly on AliBaba, but I'm super apprehensive as I was with AliExpress. Unfortunately I'm unable to use PayPal or a credit card through AliBaba due to...

It's been a few months since checking in with this thread. As of today, I've been scammed by two AliExpress purchases for 8x320AH batteries and about to get scammed by a eBay seller... They're supposed to be delivered before Jan 4th... not likely! I thought eBay was the smarter choice as I...

@Rednecktek now I completely understand why I would need a crap load of screws and what you were trying to do. However, if I screwed everything in as it stands, I'd still have an uneven floor that's less likely to shift/warp. If I was able to get the shed and floor level, than your process...

@Supervstech unfortunately, sealing the underside is not realistic right now. Not much room under there.. maybe 4". I might be able to drape some poly from one end to the other, but I wouldn't consider it sealed. @Rednecktek thank you for the suggestions. Any thoughts on just using this ? If...

Thanks for the suggestions! I agree, OSB is not ideal, but redoing is not an option. I think i'm going to install some Dricore Subfloor while leveling it with some shimes or inserts underneath it and then either carpet or plank flooring

I think I need to setup the diesel heater in the attic, with a fuel tank. I anticipate seeing -25^C for a couple weeks this winter and keeping things in the attic will keep it out of the elements and a little warmer

Ceiling is fully insulated with R14 Rockwool. I'm getting confused by the suggestions... if I understand correctly, 1/2" foam board then 1/2" plywood? How would that cope with the continous warping of the original subfloor?

Great suggestion. It's sealed with some window gasket tape and has Rockwool on top of it as well. It's a tight seal to begin with and is not fully shut in the picture

Unfortunately, woudln't consider it "Stable" as it warps/shifts throughout the year. Also, I don't have 4-6" of space. I have maybe 1" tops between the bottom of the door and the current subfloor

In the process of converting my shed into an office. It's coming along nicely! This post isn't about it being off-grid or how it'll be heated, there are other posts about that. But because everyone has been so helpful within this forum, I thought I'd seek for some flooring advice. As you...

Hi Everyone... Thank you for the response! Great advice! (@OffGridInTheCity - thank you, some answers below) The walls have been insulated with Rockwool R14 (2"x4" thick walls). The interior OSB wall joints/gaps have been filled in with caulking, while the majority of exterior OSB...

I've recently converted my shed into a small office (~100sq ft). The shed is now insulated with OSB walls and will be somewhat offgrid as I have ~2000W of solar going into a 24V 320AH battery bank, with a Growatt all-in-one 24V inverter. Yes, I know the 320AH batteries may be overrated.... I'm...

Thanks Choco... I'm pretty sure I saw your post earlier and have captured everything you stated. Thanks!

Wow this thread has blown up since I was last here. So, officially... Scammed by both Assembly Batter Shop Store & Jinxin battery 18650 Store. Apparently my batteries have been delivered and nope! I've waited the 30 days for Aliexpress to step in and wow... useless! They're asking me to...

So far i've ordered from the following: Assembly battery shop Store - 8x320AH toal = $1000CAD -> Super shady! Shipping was supposed to be through DHL, but only got a tracking number that can be tracked on 17track.net (shady!). Currently in talks with buyer as they were allegedly delivered more...

Actually?! That's crazy!

I keep asking the seller for the Canadian Carrier details, relevant tracking # and proof of delivery. They keep sending me a link that just takes me to sale details. I'm pretty sure it's a dead end with the seller and I really don't want to wait 30+ days for Aliexpress to step in. Any harm in...

I may be a victim....What do you think? I purchased 8 of these cells through AliExpress. Paid roughly $1000CAD for all 8, which included shipping. They were supposed to be shipped through DHL. These were a good deal, not the cheapest, but not the most expensive as well from what I could...

@derekisastro Thank you for your response! This question is not on topic of the inverter, but hoping you can still answer.... It's regarding BMS's. This will probably be a very novice question, so forgive me.... BMS's are rated for different amps.... If my battery bank will be 310AH, I don't...

^ just as a follow-up... after further reading, it sounds like if I'm using a homemade LifePO4 battery bank, with a BMS... It's unable to communicate with the Growatt unit and I therefore need to adjust some settings.

@derekisastro Thank you for your response! Yeaaaa. Disregard the 1500W/1800W comment. I had a different electrician over today... All is good :) Initially I was leaning towards the MPP LV2424, but I'm now leaning towards to Growatt because it's potentially quieter... but it produces more...

*Bump

First, my apologies, I know there's a couple threads surrounding this topic, but I'm still unable to find the answers I'm looking for. I have a shed I'm converting into an office and want to power it off grid, with a AC input for charging batteries The plan: - 24V 310AH LifeP04 - Homebuilt -...

Thanks for the insight! I'm definetly thinking about soaking the wood with some water and borax.

Alright, I'm so lost with the conversation about heat exchangers and HRV's.... what? haha. To clarify, the attic to the shed is ventilated.. there's vents in the roof and soffits. I'm also now leaning back towards R14 Rockwool for insulation. I was really looking forward to spray foam because...

@Steve_S what are your thoughts on Spray Foam for insulating all of the walls and possible above the ceiling? https://www.homedepot.ca/product/touch-n-foam-professional-touch-n-foam-professional-2-component-spray-foam-insulation-kit/1000718744 It looks like it's Class 1 Fire Rated. Less...

@Steve_S Thank you for your response! I'll consider using Amy Wan for my cells in the near future! As for heating, i'm still considering all options, particularly electric in-floor heating... one problem though... The shed doesn't sit on top of a concrete shed. It's ontop of a couple 4x4's. As...
