I'm really happy with the BEL fuse I found at 7$us (Newark). Nice tiny/compact fuse for lower amps application (25-180A) with AIC of 30kA at 50Vdc. Perfect for my 35 kWh LFP battery.

That it for the 3D model. I decided 35 kWh will be enough for me. You can see the 3 modules 11.7 kWh each. They will be fix with the 3 green channels in the rear. Modules and channels will be fix together with M6 screws. The purple parts will have M6 nut weld on it and will be slide in the...

I confirm! Here a picture of the 360Vdc EV battery (Chevy Bolt) connect to the MPPT of the Inverter and a small 24V battery connect to the battery input of the inverter.

The 6000xp is the best example today. At only 1400$, with 50w of idle consumption and 2 MPPT input, it's really hard to find good advantages at separate components. Specially if you are not space constraint (boat, van, etc). To add, panel price are really low, so add few panel to offset few...

We convert one for a local restaurant 2 years ago with a Tesla 3 motor + a small Chevy Volt battery. What a blast to drive such a lightweight vehicle with that power. But the ride quality and road noise are terrible. https://www.st-hubert.com/en/about/70years/beetle.html

Many EV still have lead battery, but some EV start to have lithium 12V. The Tesla Plaid is one example. It have a tiny lithium battery. Funny fact, it's not a 4S LFP (13.2V nominal), but a 4S NMC, so 14.8V nominal and up to 16.8V max. I don't know about the Cybertruck 48V auxiliary battery*, but...

What!!! I want to see that 😁 As it's possible to find crash Leaf with good battery at low cost, you should have a good reason to build a battery. Greater capacity or simple challenge? Well, 25 x 4mm. That give 100mm2 x 0.6 (alu VS copper factor), so 60mm2 or close to 2/0 AWG. It's way enough. I...

Plan is to connect the PV input of the inverter via AC compressor connector of my Chevrolet Bolt (Vanabolt) because I don't use the AC. Item 6 on pic. So there is actually a 30A fuse rated for high voltage DC on the juction box of my van (second pic).

Here is the final result. Four 420W panels and two 50A MPPT. Everything work fine and it's a lot of power for this sailboat. The Starlink will caused some shade. I'm interested to know how much power will be kill by this one at different time of the day/years. Time will tell. But I did an...

Leviton spec: Amperage : 3 A / Grounding : Self-Grounding / Voltage : 34 VAC/VDC They are rated 3A at 34Vdc... man it's sure those will last forever if you switch 48V led light who pull fraction of Amps.

The cheapest way is to buy a complete crash Model 3 with 60 kWh LFP battery and sell all other parts to recover your initial purchase. The good thing with tesla 3 is the BMS, the charger and the DC/DC are coming with the battery. So 12V available and a way to charge from grid.

My cheap inverter with 450V dc input ? 1. PowMr POW HVM2.4H-24 2. 240v 3. 2400W (a bit over 4000W peak) 4. idle 33W from battery (spec 30W) 5. Power Saving:?

Here is my conversion kit ;) Everything you need: battery, charger, motor, controller, charge port, booster brake, power steering, shifter, accelerator, digital cluster, etc. All this available at your scrap yard for few thousand$ (1k$ to 15k$). The drop in kit will never exist at reasonable...

No issue, but there is a really good reason why. It's because I start the Chevy Bolt (my van) after having connect the PV wires. So, my understanding is: The Bolt do a regular precharge cycle before closing the 360V battery contactors. This could take a fraction of second longer because the...

Nice set up! It will be interesting for you to determine optimal panel angle to have maximum input every month (instead of maximum input for the year). Or maybe do you plan to adjust panel angle for winter/summer? As a guy from the north, I know now that an important angle for winter months is a...

First time I had to use my solar setup during an outage few days ago. 5 days without electricity after a tree drop on our line. Everything worked fine. My small 3 kWh battery (24V) build from Ford Fusion energy cells have energized some appliances via my 2.4kW (240V) and 1.5 kW(120V) Easun...

You can. At first the EVSE will not like to be connect to an inverter and it will refuse to charge our EV. But when you connect ground to neutral the EVSE will don't see anything strange and will allow the current to flow from inverter (120Vac) to EV charger (360Vdc) to DC-DC (12Vdc) to... the...

I received the compact unit today. I rapidly tested it with a 7S battery and connect to grid. Everything seem fine and there is many adjustments. Those are interesting to me: -Output source grid, solar, battery or mix of those -50 or 60 Hz, 220V, 230V or 240Vac output -Charge current from 2A to...

The best solar-related item I bought in 2023 is a Luxpower 6kW split phase inverter for 890$us (aka EG4 6000 XP).

The good new is you will be able to save your cells after charging them slowly (low amps, let say less than 28A for your 280Ah cells or 0.1C). I have recover LFP cells drop as low than 0.1V with success many years ago. In your case, to save your battery the simpler way is to have power...

Same thing for me. I revived many cells who hit 0.1V nine years ago and some are still used today. So 1.7V / cell is not a huge problem. Charge them slowly.

I hope no. Ton, with a S because there is many. The resulting tension create by a M12 bolt is in the range of 3000-6000kg (so 6600-13200 lbs) depending of grade, material, thickness, etc.

Sure, especially if they are not at the same orientation (east/south/west). That way, you can expect to maximize the 17A input of the MPPTs as each string of 5 panels will give max amps when sun is right in front.

You can use one inverter, but your plan of using 2 inverters is also ok. The only drawback is the inverter itself will consume around 1.2 kWh/day simply be ON. The advantage is you will have 12 kW of power (up to 24 kW peak) instead of 6 kW. The thing is, if your load are not huge (less than 6...

Why 8 times 280Ah 48V batteries instead of just one 2240Ah 48V battery? For me it seem a lot easier to connect 8 cells in parallel to create one big 2240Ah cell and connect those in 16S battery. After you need a cheap, but super nice, Zeva 16S bms and a large 500A contactor. That it, no?

I confirm. Up to 60 kW of regen for a chevy Bolt and more that for a Tesla M3. Regen is way lower if cells temperature is low. Anyhow, despite this 6 kW of solar is negligible compare to regen, there is huge chance that the EV system will not like those current coming from other things than...

First test with the saw done. I'm amazed how well it cut in this chill plate :oops: The fact that chill plate is almost empty to allow the cooling to flow result that all the wall have small thickness. The other axe will be way more tricky.

I ordered one 350 AMH fuse. The compactness, the low price and the high interrupting ratings are just too attractive ? I have hard time to believe the thickness of 0.6mm (only 0.023''). I hope it's an error. 0.6 x 17 is only 10mm2 or AWG 7 equivalent ?

To me it easier to manage only one battery instead of 8 or, preferably, manage only 16 cells and one BMS instead of 128 cells and 8 BMS. Well, I can only see one advantage to have 8 BMS and it's about the balancing current capability who will be 8 times higher. But despite if the BMS balancing...

Yes, LFP cells are supper safe and Li-Po cells can catch in fire. But everyone need to know the fact that many EV cells are not Li-Po cells, but NMC cells. Those are way safer than Li-Po. Personally, I use 6S battery for 24V and this work fine as max/min voltage (25v / 21v) match many 24V...
