How do i increase the wattage to charge my Yeti 4000?

jeciv

I tried using 3 300 watt Ranger panels to charge my Yeti 4000 and would only get approximately 500 watts so then i added an additional 300 watt panel and still cant get anything over 560 watts.

Thank you both, JaimeMagiera and Jay_Water_for_Good, both of your advise was not only helpful but it ended up working out perfectly with the replacement adapters off Amazon you suggested. Thank you both for your help.

1. Which port are you plugged into? The high voltage or low voltage?
2. Do you have your panels wired together in parallel or series configuration, and what’s the voltage on those panels?

I am plugged into the high voltage with all the panels in parallel. i purchased all the wires and panel from Goal Zero and it looks like they have discontinued selling connectors to allow series connections.

With Anderson connectors, right? You can just use Anderson to MC4 adapters, then wire them together in series.

you’d need 5 of these (one connected to each of the 4 panel’s outputs then one to take the +/- ends of the string and convert them back to Anderson).

This would give you 19.2v x 4 = 76.8v, and with the yeti’s port maxing out at 40a that means you’d be able to handle up to 3,000w of solar.

If you had them wired in parallel, and they were hitting their optimal 19.2v, the yetis 40a max would mean you’d only pull in 768w. So your 4th panel is doing nothing.

If they were in suboptimal conditions, and say pulling in 17v you’d be at 680w max (even though you have 1200w of panels plugged in. Simply switching to series would jump you up to nearly your max 1200w, if il doing the math correctly, as that would keep you below the max amperage of the yeti.

This is covered in the manual on page 10.

“If you plan to use Goal Zero portable solar panels and do not plan to exceed 600W
of total solar input, use the 4:1 HPP Parallel Combiner Cable (SKU 98061). This
will allow you to connect any four Goal Zero solar panels together for a maximum
600W of solar input.

If you want to exceed 600W of solar input, you’ll need to set your panels up in
series. There are two ways to do this depending on which Goal Zero solar panels
you have.

If you have Goal Zero solar panels of the same wattage
You can combine up to four Goal Zero solar panels of the same wattage in a series
by connecting them with one 4:1 Series combiner cable (SKU 98715). Plug the
four panels into the cable, then plug the other side of the cable into your Yeti PRO
4000. This configuration allows for up to 1600W of solar input.”

You’re right though. The 4:1 series combiner cable is no longer available in the GoalZero shop.
