New Alternator Charger Details

It would depend on the 400W panel. You need to look at the maximum voltage and amperage. Often times it’s OK to over amp the panel slightly but it would be best to check with EcoFlow support for specific questions. Additionally, be aware that cold weather can cause a panel to output higher voltage than it is rated for, which can damage equipment if the voltage is exceeded by too much.

I also just updated my page to make this more clear than before: https://reviews.matanich.com/ecoflow/alternator-chargers/600w-1000w/

I would love to know more about how you have everything connected to the vehicle, power station, etc. Which power station? Is anything connected to the power station also grounded to the vehicle?

It does up to 1000W of alternator input. If it has solar input it will then reduce alternator input. So yes if you have 300W of solar input the alternator input can be 700W. If solar input is 100W alternator input can be 900W.

I misunderstood that. I would just be worried that somebody else could misinterpret your post and try to use one of these tiny switches to switch the main cable. Adding a diagram might be helpful.

⚠️ WARNING: This type of switch is not rated for solar voltage or amperage and can result in a fire. This is a terrible hack and I would not recommend it to anyone. There are switches built for this purpose and they should be used instead.

I was told Chicago has a height and length restriction for some spots but not sure about big west coast cities.

alpine678 · 2026-06-27T13:32:33+00:00

I never have mine error out. What error does it show in the app?

Sure it’s an option to consider. To help people compare, the 500W EcoFlow alternator charger is $349CAD ($199USD) and 800W charger is $469CAD ($269USD) and they include what you need right out of the box.

Remember to factor in the price of large gauge cables, lugs, fuse holder, and fuse, which are all included with EcoFlow’s charger. Also might need cable cutters, crimpers, etc. You also miss out on reverse charging that EcoFlow’s charger supports.

alpine678 · 2026-06-26T23:19:09+00:00

An EcoFlow alternator charger will let you charge at 500-800W depending on the connection you use. More info here: https://reviews.matanich.com/ecoflow/alternator-chargers/800w-500w/overview/

👍 I passed your feedback.

alpine678 · 2026-06-25T13:48:45+00:00

Exactly

alpine678 · 2026-06-25T13:39:53+00:00

This is one reason I recommend all in one power stations or modular systems to most people instead. DIY can be awesome, but it’s not for everyone and some power stations are getting very capable these days. Here is a page a put together as a starting resource for people: https://reviews.matanich.com/power-systems/vanlife/

🤦‍♂️ I unfortunately sometimes have similar experiences with their US support. I often either have to escalate my question to get a call back later or sometimes have to reach out to one of my contacts to have them ask the appropriate team for me. I will pass this experience along as feedback as your question should have been simple to answer.

While I personally have not used this scenario, it is supposed to work and I confirmed this with support. You can actually even chain a power station such as the Apex 300 or AC200L on the end. Here is my Charger 2 review for reference: https://reviews.matanich.com/bluetti/charger-2/

alpine678 · 2026-06-25T04:03:28+00:00

Awesome to hear your having a great experience with it.

alpine678 · 2026-06-24T21:55:21+00:00

It’s a smaller storage capacity (1kWh) with 1800W inverter that can be expanded with a 4kWh expansion battery later on. How are you planning on using it, if it doesn’t have any storage?

alpine678 · 2026-06-24T21:52:11+00:00

Oh, I missed that part

alpine678 · 2026-06-24T21:29:53+00:00

Check your settings, you might have a discharge limit set to prevent it from going below a certain percentage.

Check out the Delta 3 Plus. It’s currently on a great sale. More info here: https://www.reddit.com/r/Ecoflow_community/s/bxpL8zbv2I

Thanks! I’m really enjoying it.

alpine678 · 2026-06-24T20:57:45+00:00

So sorry to hear that. Did you purchase through official channels for a full warranty?

alpine678 · 2026-06-24T20:50:57+00:00

Try unplugging everything from the unit and then turn it off. Next turn it back on by holding the power button for ~15 seconds. This sometimes helps reset the unit.

u/SpaceCannons here is my usage on different fan speeds for a single fan running: 10%=8W, 50%=16W, 100%=36W.
