So the Tiny Ohm is coming together more and more. My setup has evolved from a Goalzero 1500x to what you see below. I hope to wire it all permanently pretty soon, just mapping the wiring out and trying to figure something out for better temperature control.
I went this for the portability of using it in other campers, plus it is silent. It has a 2000W AC (3500W Surge) inverter allowing it to handle surges from power tools, medical devices, and home appliances, including full-size refrigerators.
I’ll set this up and run wires inside to the yeti. I’m looking for better solutions, but this is what I have and it works fine. As of now, I store it under the bed when not in use. The issue, though a first-world problem, is it takes around 9–18 hours to get a ‘full’ charge. (better solution found and listed below, see Victron 30 amp external MPPT and 175w panels)
This works great if I want to top off the 11500x. I just move it to the car and plug it up while I’m driving. I have an alternator charge system that I’m working to install, but it’s more complex. This gets me by.
7‑pin Upgrade
This is so I can charge the system while driving, see next point.
I’ve upgraded the 4‑pin to a 7‑pin and ran wires from the vehicle alternator into Tiny Ohm. This charges the system while I drive, and automatically shuts off when the car is turned off. That way it doesn’t drain the vehicle battery. This is powering the battery tanks, not the actual yeti.
This is strange because they aren’t lithium batteries but it works. One day maybe I’ll swap them out but this increases the capacity of the 1500x by 2.4kWh. I now have 3900 kWh Total. This recharges by the Expansion module which uses the Victron DC Converter. PLEASE NOTE, some folks on youtube have figured out how to wire lithium battery tanks instead.
I bought this directly from GoalZero, so it’s preprogrammed, but you can buy it anywhere and DIY. The reason for both Victron additions is to increase input for fast charging and for redundancy. This particular unit allows for max input from my solar panels. Since it is external I can also use another charging method simultaneously like the alternator or high-speed shore power.
I’ve now mounted these on the roof. They wire into the Victron MPPT and should provide 525w in optimal conditions.
Exterior Outlets
I’ve added this Noco Dual receptacle box. I still have the factory power plugs on the driver’s side, but this Noco outlet was added on the passenger. On the interior, I plug the High-Speed Charger into one outlet and the tank charger into the other.
I’ve also added this solar plug next to the Noco. So although I have solar panels on the roof, I can still use my boulder 200 case and plug it up to increase my solar power. This is mainly used while boondocking.
I’ll get some better pics one of these days
