#1: Goal Zero Lithium 1000 (recommended)
When it comes to goalzero, you should avoid the small/extra-large models, and the overpriced solar panels and the accessories... but if you buy the latest lithium 1000, and combine it with their high efficiency MPPT charge controller add-on, you will have a great little system! It works great, and if you add 300 watts of solar, it will charge pretty fast. This is my current favorite after testing a lot of generators. I used to love the Inergy Kodiak/Apex, but the output was horrible and the goalzero destroyed it in numerous ways.
This system is so easy to build that it takes minutes. The hardest step in building a system with a goalzero is mounting the solar panels and running wire through your roof to the goalzero.

Best value and performance goalzero combo:
- 1045Wh lithium portable power station can power up to 10 devices at once
- Patented AC inverter (output, pure sine wave)
- Charge phones, tablets, laptops, cameras, drones, and more. Powers your refrigerator, blender, TV, lights, power tools and medical devices
Unfortunately, the mppt charging module has been out of stock intermittently. If you can find one, and combine it with the 1000, you will be set! Be prepared to spend extra money for adapters to connect the lithium 1000 to your solar panels (or make your own). This will allow you to connect the lithium 1000 to practically any solar panel available (as long as the open circuit voltage is under 22 volts). Be sure to use MC4 branch connectors that will wire your solar panels in parallel! If you do not, you will destroy the lithium 1000.
If you want to upgrade your lithium 1000, upgrade the MPPT to a Victron!
This will increase the output in low light conditions, allow you to do custom charge cycle limits (charge to 90% instead of 100% so the battery lasts longer), and push more power into the battery. If you want to do this, check out my video tutorial:
