Rosco gets a treat and I run my house off-grid with MPP-LV5048's and 8 BYD LiFePO4 batteries.

https://www.alibaba.com/product-detail/LFP-Lithium-ion-Battery-Lifepo4-280Ah_1600128023170.html FYI, 64 cells in a 48V setup. 51.2V Nominal at 280ah = 51.2x280x4=57 kWh $5398 total, with trade assurance, shipping, everything. = $5398/57 kWh = $ 94.13 per kWh, DELIVERED.

Hydraulic Crimper Cable Bender Ratchet Cable Cutters Cable Stripper These are 4AWG to 4/0 AWG. If you are doing 250 MCM, you probably already have professional tools. I prefer the 16T crimper instead of the 10T crimper because the 16T holds the dies in from both sides. I just did a project with...

The parts: (and links) 295w used solar panels (I've seen 248w from them already! They are polycrystalline, big and heavy, way overbuilt for residential use.) Ebay Superstrut Lowes Threaded rod hangers (Sammys 3/8-16 for wood) Ebay Sammys 8113910 - #14 Nut Driver Ebay Bolts to hold the...

I have two PV setups. A 6.2 kWp grid-tied and a 3.4 kWp off-grid. I have a Chevy Bolt EV. 1000.0 just clicked over on the trip odometer. 100% off-grid PV-Solar provided

This is now officially a legitimate sickness. My 4th off-grid system: The players: This setup is actually cheaper than going with a PWM Hybrid all in one unit 48V unit. I have AC input to charge the 48V batteries with shore power. (The 21.99 charger) A way more than I will use MPPT battery...

I'm putting a net meter on my on/off-grid setup. The players: This looks pretty straight forward. :) Some 6/3 service line (lowes or home depot) A service meter thing. (Missouri Wind and Solar) A real live net meter. (Ebay) Connects.

Yesterday with tree shadows, today without. MPPT 2 is the ground mount MPPT 1 is the flat roof-mounted panels. 4 MPPTs in all. MPPT 1 on inverter 1 is the flat part of the roof. 4 panels 4s MPPT 1 on inverter 2 is the flat part of the roof. 8 panels 4s2p MPPT 2 on inverter 1 is the top row...

Next time you need a copper bus bar, go to Lowes/Home Depot/Menards and get 5 FEET for about $7. Type L is thicker than N or M. Cut+Smush+Drill = Bussbar. Add some heatshrink in the middle to get fancy, or use a garden hose to hide the copper. No, it's not tinned, but it's still copper! Don't...

It's funny how the Chinese New Year completely disrupts the entire supply chain. :) I have my harnesses all made, my BMS's ready to go, and 8 cent connectors somewhere in the universe are holding me up connecting the two BMS'es. I am using AnyDesk to remote into the tablets. The tablets are...

A no cut, no splice, plug-n-play. It has a screen, Bluetooth, and more settings in the app than we know what to do with. Will already reviewed this BMS. The Inside wires: The Outside Wires: Conclusion: Molex Micro-Fit 3.0 430251000 10POS 3mm Molex Micro-Fit 3.0 or 1729521001...

The battery is from 2018, new then, but has been 100% submerged in rainwater for two years, outside. The charge controller is the absolute cheapest Amazon PWM available, I think I paid $8.50 for it. The panel is a 72-cell panel, but half are disabled. I suspect a broken solder somewhere. It was...

I just got the email from Peggy Hung from mppsolar.com, deliveries "will be ready in 10 working days". I don't know if the actually means they will start delivering them on November 27th, or it takes them 10 days from when you order them. (I think it means the new inverter will start shipping on...

My panels are 295W rated, and used. I just saw 282W with 824 w/m² 9 of 12 panels installed(temporary setup), 3s3p

Seeing the leg/cliff starts at 50.7V. Two hours later 49.6V. One hour later 47.6V. Ten minutes later 46.0V This is roughly a 60 kWh battery with about 800 watts of continuous draw. I have the inverter shut down if/when the battery reaches 46V. I used to have it set to shut down at "10%", with...

"Solar panels only work when the sun is out. " Hold my beer... And just like that, the anti-solar panel, for night time power. https://www.eurekalert.org/pub_releases/2020-01/uoc--aca012920.php

I just bought one of these::cool: So now I want one of these. :ROFLMAO:

Just 20 minutes earlier I might have had enough Sun to see some watts going in. But nooo, the earth had to just keep turning and make it hidden!:rolleyes: 4 Panels, 2 in series, then paralleled. 60~115V (145max) 2 in series VOC was 80ish volts. 295w used panels. I'd take a photo of the panels...

I just finished this for my setup. Tomorrow at least one circuit is getting used! My cat doesn't need a throne!

Yes 100% 0% 100% is a cycle. That's what the Lithium battery is guaranteed to do 3000 times, and then have 80% capacity of what it had when new. So if you only charge to 80 and discharge to 20, it is expected to have 5000 cycles. So the question is, what actually is a Cycle? When does...

You can have others tell you what they think your solar potential is, or you can just measure it directly yourself. I found a weather station that has a w/m2 meter on it. 1000 w/m2 is "The Standard Test Condition (STC)" used for the output of a solar panel. My "sol" meter (and weather station)...

In the meantime, it's a beautiful sunny Kansas day. I have 119 kWh to go before I am back to Zero on the Net-Meter. I have been 100% solar charging on the batteries for 10 days today. Still charging the batteries while running the house. And about as perfectly in the balance, as can get...

Right now my 12 panels, 3.5 kWp off-grid setup is producing 3.3 to 3.6 kW, it actually peaked at 3.81 kW. What's more interesting, it is a very thin cloud cover, not clear blue skies. Temp is 71°F

Remote control and setup of course. Ingredients: 4 Samsung Galaxy Tab A SM-T580. I imagine any android tablet with Android 5 or newer will work. 4 ANT-BMSes Bluetooth app on the Tablets. A USB Power strip Google Wifi (mesh wifi) Laptop (Old HP) Anydesk on the remote desktop and everything you...

If you happen to be on the fence about going solar. Maybe this will be a little bit of a reason to sway you some. Last year it was $104.98. (This is the minimum connection fee to have the grid-connected) Most Utilities are soon ending "buying your solar" and going to credit only system. In...

Yuuup. I also charge all my rechargeable power tool batteries with the solar. Lawn mower (40V Dewalt), Trimmer, Blower, drills, everything. :)

This unit is a modified European version to match USA voltages. Unlike the LV6548, the LVX6048 is 240V Split Phase in one box. The LVX6548 does not show or mention support for 3 phase. Page 28 Grid-Tie Operation 6kW and 450V MPPT (100-400V range, 27amps) 9 can be stacked in parallel for as...

Happy Earth Day, 2021. Yesterday I did some tree pruning with my "yellow" pole saw and regular saw. I used one 20v 5ah battery for all the cuts. I used the garden dump attached to the Z6 and made about 8 hauls from the front to the back, and then mowed. I finished and the meter indicated an...
