Power station, solar panel issues

I have an Eco flow Delta and I just bought a 350 W Grisel portable solar panel. The voltage and amps are within the maximum range for the power station. When I plug it in though the wattage goes all over the place. It goes from 10 W to 80 to 100 to 200 to 300 and then back to zero, and then it cycles all over again. This happens all within 20 seconds. There’s no stable charging. Does anyone With electrical knowledge know what could be causing this? Could it be a faulty solar panel? I’ve never heard of a faulty solar panel, but I guess it could happen. I’ve also tried different cables and the same thing happens. Any help will be appreciated.

 

Take it to someone who knows what they are doing. Or read the instruction books...

 

Are you plugging it to the AC socket in the 4runner? If so, some batteries cannot accept the 400 amps the AC converter is capable of putting out. Reason being is the current from the car’s AC inverter is square wave, while many battery power stations require pure sine wave charging input.

Basically the power station starts to take in a charge, then it senses it’s not pure sine wave, then shuts off the charging. It will keep clicking on and off, each time shutting down once it realizes it can’t do anything with the power coming in.

This is what happens with my Iceco pb1000 power station. It’s actually capable of charging at 800watts from AC, but it won’t accept 400w AC from the 4runner.

However a neat trick that I learned with my iceco battery, is that it can accept 200w from the inverter, if I limit the iceco battery’s charging input maximum to 200w, by pushing the eco charging mode. But that only works when the car is parked (and transmission in P) and I turn on the inverter on the dash. For some reason, I can’t get to charge using the 100w mode that the car switches into when the transmission is in Drive. I’d be happy with 100w while driving, unfortunately the only thing that will allow that is to replace the factory inverter with one that outputs pure sine wave.

So basically, I can only use DC charging which gives me around 30watts, and usually is only enough to maintain the battery level with the fridge plugged in. If I had solar mounted on the roof, I could boost it a bit more I think.

 

I’m not using the AC inverter or the cigarette plug in the car. I am using a solar panel, 350 W the volt and amps are in line with the power station.

 

I see. What does it do when you charge it via the 12v socket, through the inverter, and with AC current from your home? If any of those give you stable charging rates, that would point to your solar panel I suppose.

Especially, if these fluctuations with solar are happening with completely unobstructed sunlight.

 

Have you ever used solar to charge it in the past? I have an older eco battery and my solar works great. Do you know someone with solar panels that work?

 

If it does not charge properly off of other sources, it could be a battery going bad. I had an EcoFlow Delta 2 fail at 3 months old. I sent it in and they said that the battery failed.

 

When I charge it to the AC plug or the car, it does charge stable. I also have another week or solar panel where it does charge low wattage but stable. I ended up returning the solar panel and getting a new one to see if the problem was the solar panel. I will update once I receive
