Yet 1400 (original) - Fastest Way To Charge using all inputs (mppt included)?
I was trying to read old emails (from support), the manual and the stickers on the lid/MPPT controller about how the charge process works on this original 1400, I found myself getting a little confused. So, I will ask here in the hopes someone can re-direct me to the correct FAQ (tried this, failed miserably) or give me the cheat-sheet lowdown on what is safe and what is not.
If wall-power is available, is the fastest way to charge a Yeti to use the Goal Zero 25amp Fast Charger via APP to the MPPT Module + a Yeti 25amp Fast Charger via APP to the PWM module built into the Unit? Can you also run the standard (or a bank of standard) 8mm Goal Zero charger bricks (the included one) into the under-the-lid 8mm port as well? Or are we really beating the poor thing up at this point? This would be I have no power but can get somewhere that has it, and want to minimize the charge time back to 100% scenario. Thoughts?
If wall-power is not available, and solar is, the fastest way to charge a Yeti 1400 with MPPT controller module is to run, say, 500 to 600 watts of Solar (rated, not actual output of the panels which will be less) into the MPPT controller (making sure never to exceed 30v (ok, really 48v, yes?)), and pumping 400 additional watts of solar (again not going over 30v) into the PWM controller side as well. Is there any benefit to also adding 200 watts of solar to the under-the-lid charge controller as well?
Summary: This old girl charges kind of slow, using whatever energy is available I'm just looking for the quickest way to get her up to 100% again when needed, but doing it safely.
Side-Question: When feeding in power via the APP connectors, are the 8mm inputs on the PWM and MPPT controller ignored or does all that input 'stack' so to speak, I guess I just need hard limits so I know not to overload. Appreciate the feedback in advance, Thank You.

Hello @HR1 ,
The Yeti 1400 is actually only rated from 14-22V and up to 30A on the High Power Port (APP or HPP) and 14-22V up to 10A on the 8mm. The Solar Optimization MPPT Expansion Module is rated with the same specs as the Yeti.
To answer the side question first: Unlike the Yeti X series where only one input will allow power at any one time, you can input from the 8mm and the HPP at the same time (Photo with input limits below). If you are inputting a full 360W from the HPP port however, teh 8mm ports will not do you much good as the charge controller's max input is still 360W regardless of if it is all in through the HPP or a combination of the 2 8mm ports and the HPP.
Using the MPPT Module at the same time does allow an additional 360W of input, from shore power or solar, in the same way. The Yeti's built in charge controller is not as efficient with solar input as the MPPT Module so we would recommend using the built-in ports for shore power and the MPPT Module for solar but if needed can be mixed an matched according to your situation.
The included image is taken from the old page for the 1400 Yeti but the outlined specifications are a match for the solar optimizer as well.

Thank you very much for clearing this up for me.
If shore power is available, I assume it is safe to run the Goal Zero 98080/98081 25a Fast Charger into the MPPT first and, if I were to obtain a second one, into the HPP side as well so both charge controllers are effectively maxed out?

@HR1 ,
Yes, however that cable is no longer in stock on our website as the lithium models have been discontinued for so long. Getting them on Ebay or similar websites may not necessarily net you a working one but that and other similar sites are the only way you could obtian the lithium 25A fast chargers at this point.

Understood, thanks for helping me sort this out.

Actually, I need to follow-up one more time. I have my manual here and it says on page 4 that when recharging, Voltages in excess of 30v are not supported, not 22v. Is it 22v or is it 30v? Thank You.

@HR1 ,
Please limit to 22V. You can check our website for an updated Userguide that has been refined and corrected on our website.
