Was building a Stealth-Sleeper and decided to add 150w panel direct to rack, cheapo charge controller, and smart box with a mice 75Ah SLA. Added in an RV light to make it official lol. (not my finest work but it was pro-bono)

For what it's worth (and it's pretty poor), here is a battery warmer I made for the LifePO4's for central Ohio, in an outhouse. (2) 10x20 17v 120v plant warmer mats (no foam padding). (1) Amazon temp controller that we also have in the coop. 3/4" foam board, 1" foam board, a full roll of foil...

https://ktla.com/news/local-news/california-power-companies-roll-out-fixed-rate-bill-proposal/ So if I'm understanding this right; everyone will pay $0.33 per KWH (which is INSANE compared to Ohio right now), but then everyone will have a 2nd charge based on household income? It's that a fine...

So my micro system just wasn't doing it for me. Being past broke but never throwing anything away, I made a micro Utility Backup for it ROFL! Enjoy

Will will be shaking his head saying "this is not what I'm teaching here" lol Honestly though, for my sake and others please feel free to point out fails in this system*

Hey all, had an issue today. Woke up and the 24v LifePO4 7000wh bank was idling due to the controller having low-voltage-off sometime overnight. Currently waiting for solar to bring back up to cut-in (recovery) voltage. The cut-in voltage is 25.2v, the bank is showing 23v & 30% on the...

So after learning the OOYCYOO Controller doesn't actually work on LifePO4's.... And after a hard lesson in idle consumption of the OOYCYOO & the 24-48 Booster..... I then learned I could go 48v & get a much better setup for the $$$. I now have the follow running since this morning. The (2)...

Week 4 I think on the ECOFLOW Max. As the title says, last night I switched the rotor switch from ECO-Off-Utility & then the mini-fridge started Clunking like a Model-T for 30seconds then gave up (but still works)???? So this was on utility. Thoughts? Also, every so often on the ECO we get...

EagleRise 5kVA 1:2 or 2:1 (Buck/Boost) transformer: This transformer was bought for a $500 for my son's camper he was full-timing in on the homestead, which sold this weekend. It has been mounted on the side of the cabin since 2019 out of the sun, and is in great shape! Never saw more than...

Ok guys, who can figure this out?? Windmill (0-80RPM) Flywheel (170lbs) Drive sprocket on Windmill shaft: 60T Input sprocket on Midshaft: 16T Output sprocket on Midshaft: 75T Input sprocket on Generator: 25T Generator: 90vdc Gearworks JM5-001 (4200RPM, 1.7HP) I have sadly about all but given...

As I awaiting building up fund for batteries & inverter..... I have a 1.7hp 90vdc Gearworks motor (4200rpm). I plan to chain-drive this to an A-Synchronous Motor plugged into the grid power. I know one could grid-tie by over-clocking such a motor, and I still have some math to work out...

Hi all, looking to see you thought on having two MPPT controllers share the same DC line (and the same array of course). This would be have two Ecoflow Delta Max 2000 sharing. Thoughts?

I want to have two Ecoflow DM's side by side. Can two MPPT's share the DC Negative conductor as long the wire size is correct? Example: If I had two 1200w arrays, 83vdc, feeding two 800w MPPTs. Could they share the negative conductor? Thanks!

So what starting building a solar power station 2years has now brought us to this: (24) HQST 12v 100w panels with a clear southern view in Ohio. 12 Poly & 12 Mono. (6) strings fed into a 6 string combiner box, reverse diodes, surge, fused. Then into a 32amp fused Siemens disconnect. Then a...

Hello all, All the calculators ring out ok, but will paralleling 2 #12 THHN be A-OK for a 50' run from my PV Combiner box to my MPPT Conroller? I have 3/4" conduit already buried & had the THHN so ran it. 80vdc - 30A -2400w Just wanting your thoughts - Thanks

*I am not a professional, just doing what I can with what I have*

Good day all, hope to get some replies here: My panels on the chicken coop are 120' from the Ecoflow Max 2k. The Eco MPPT pulls in 800w. My 24 100w panels are in (6) strings of (4) panels. All strings fused, dioded, surged, 15A DIN breaker - then to a Siemens fused disconnect with 15a FRS...

Well it's been over a month and all is working fine, have only have to switch back to utility twice for the night. Thanks again for all the advice on here.

Ya know, while buying the parts as we could afford, I binge watched more than proper youtube videos. I now KNOW how many were BS. ANYONE saying "Get the max out of your generator" while using 380-400w array is BSing us! Don't be fooled, load down on panels. We overpaneled 300% on an ECO, and...

I bought this 2years ago, and it's been running off my 2400w array (66% Load) since. As our Ecoflow died, we upgraded to hybrid inverter and no longer need this gem. No fans, great heat sink, great design. $75, you cover shipping.] HQST 60 Amp MPPT Solar Charge Controller 12V/24V/36V/48V...

Hello all! I purchased a few of these for our commune. I am selling the following unit as after finally getting down to hooking up an Eco Delta & Rotator Switch I just don't feel like stuffing this into the panel. Ordered Oct 2020, and it's +-<1.6% accurate comparing to our utility's monthly...

Hello all, I have a pre-feed expansion battery setup for our Ecoflow Delta Max. The solar & battery bank are controlled by an HQST 60Amp controller with a 20A output. I know it is something with the Ecoflow causing this: If I turn off & on the Eco, just about 24hrs later it will cause this E4...

Hello all! I have two arrays now mounted (one fixed, one tracking). One array has 12 12v 100w HQST mono panels, the other 12 12v 100w HQST poly panels. I am confused on CHARGE CONTROLLER PV VOLTAGE: Example; 12v panels put out 18-20volts... SO; Is a 48volt PV input made of 4 12v panels in...

So this is where we've ended up after 6months of putting this together. Runs fine & haven't had to touch a thing since we figured out a few kinks. Hope it helps someone :)

Hey all! So this Ecoflow Maz 2k is working out GREAT on our 2.4kW array, but we are lacking 6hours at night & not using 1600w of panels during peak hours.... So rather than a battery bank, we thought get a 2nd same unit for the extra storage, and then if the primary unit dies we can simply...

Ecoflow Reconditioned Delta Max 2000 for $680. We ran the crap out of ours for 23 months and it started flaking out. Still have another year on the warranty* Ebay Listing: https://www.ebay.com/itm/286329715676

Update: The OOYCYOO charger was: Only pulling 1600w off my 2400w array. Funks out to Error Mode once a day. Would only charge LifePO4's to 42%, then 85%, then 60%, then 100%, then..... did NOT matter the conditions, and finally it DRANK power like a bar all night long! -So out it went...

A "small" project: Have a 12-24vdc pump coming from Amazon for a fountain. I have 2 25w panels 30ft away on the well tower. I can't think of any reason why I couldn't just run the PV direct to pump. -Thoughts? Pump...

So my 83vdc array feed runs into my Ecoflow Delta Max 2000. I want to put a 24v battery bank in the outhouse 200ah LifePO4 for overnight charging. I only have a single 2 conductor feed running into the Eco in the cabin.... So with blocking diodes could they just share the same line at the...

So being a newb on here, and being a poor homesteader.... it amazes me at some of the system you all list on here! Crazy Please list your 1st system & then how much you have cashed out to date - this will help beginners in different ways :) I'll start: (2019) 100w briefcase, 300w inverter for...

So following my recent posting on this project: https://diysolarforum.com/threads/i-stopped-trying-to-figure-out-the-gtr-voltage-of-this-dc-motor-geezzzz-win-bragging-rights.55844/ 1st Video: Here is what I came home to :D 2nd Video: Then about an hour later :( Now just waiting for the...

Want to mount a 14" 80w radiator fan for a roof-vent in the pole building. Will a simple 100w panel direct-wire run this ok? Seems tight on the numbers but don't want to buy another panel..... This is just to help vent the pole building when the sun is killing it. -Thanks

We started a commercial job where a previous TJ-Maxx left some stuff, including two UPS's. The power had been down for two months, both units were still wired in but are dead and I don't have the time to mess with. Make offer but LOCAL pickup only in Newark Ohio (or you pay someone on UShip to...

We pulled this from a TJ-Maxx that moved out, this was being fed from a 2P30A Breaker, and was feeding a "DP" panel. I do have the feet fo floor usage. The whips on the back got smacked by the Sinergy unit, so it needs new metallic flex but the wiring is fine. Also shown in pic, one of the...

Update: Ecoflow Approval note down in the thread. FYI, Week 5 no worries. Well now that's sad. Got the Delta Max in yesterday. Have it hooked up to 2400w of panels... then this.... Sorry all, the officials won't know today it seems.... OverPanelling: Keeping the voltage in limits but added...

Hi all! So we have a 6' HeAvY windmill 30' to the shaft. It is fixed facing west (prevailing wind in central Ohio). 90% of the time she spins "forward", but 10% of the time it does spin in "reverse". There is a 35-chain sprocket & V-belt puller on the end of the shaft. I plan to chain this...
