Any advice or anecdotes would be great. About a month ago I bought the GoalZero Yeti Core 1000 ($900 on Amazon and I had $200 gift card), and itβs been riddled with problems.
First unit arrived scratched and dirty, so they sent another one. Second unit arrived with a damaged Anderson port that broke my solar panel.
They sent another Core unit and a replacement solar panel with the expectation that Iβll return everything theyβve sent me. I have to wait for special HazMat FedEx boxes to be sent to my friendsβ house (I have no permanent mailing address) before I can return the damaged core units. Itβs been 3 weeks without word about these return boxes.
Now this 3rd core unit is having minor, but annoying, issues, and Iβm worried I got swindled into buying the official, yet cheap, knockoff of actual high quality GoalZero products.
Iβve expressed my grievances to the company and they sent me a $20 βcrush lampβ that barely lights up my car (I sleep in a Subaru Outback).
I just went ahead and asked them if I can self-repair the ports of the defective units, keep them, and just move on with my life instead of holding onto 3 batteries in my car (2 which are technically not mine) and waiting for the return boxes. I doubt theyβll agree, because damaged units are so valuable to them since they can resell as refurbished for 66% of the cost.
Has anyone experienced something similar? What would you do here?
Hi, I have a portable power station Ctechi T240 (240Wh) which can be charged by a solar panel (100w max).
The power station is supplied with an MC4 twin cable to barrel jack connector (the barrel jack plugs into the power station).
I'm looking for recommendations please on portable solar panels with the MC4 connectors please π
Hi, just a quick question hopefully someone can help.
I have 2x 100w linkable portable solar panels with Anderson cnnectors. They are outputting 18VDC/5.5a max. I don't want to buy any more panels.
Just here to ask if anyone could give a ballpark figure of how much I'd have to spend to use these to power a decent size battery that I could run ac devices off, such as heaters, power tools etc. Not all at the same time, but say capable of running 1000w devices 230vac.
I've no idea about li-ion, lipo, deep cycle or anything about batteries, I just thought here might be a good place to ask.
The "solar battery generators" sold on Amazon are way it of my price range, I was hoping it might be cheaper to make my own?
Thanks all
This would function similarly to how a molting salt solar facility works. Mirrors would focus light from a wide area onto a container filled with salt water turning it to steam. This stream would then be fed through a stream turbine then condensed. The fresh water then could be purified and used in municipal water supplies. The power generated from the turbine could be used locally or even be used to operate a membrane desalinization process to increase the fresh water output.
Since water boils at a much lower temperature than salt melts the collection area needed would be much smaller so plants would be smaller.
Now that I'm thinking about it I'm pretty sure molten salt solar plants use steam generated from flashing water on the molten salt to power a steam turbine so literally just having one of these plants on a coast with a continuous supply of salt water.
Say I get 100 watts draw from the solar panels and use 100-watt fridge. Does the energy go directly to the fridge or does it go to the battery? Like what I'm wondering is does it degrade the cycles of the power station?

Bluett's much-awaited Apex solar generator or EP500 to be unveiled at CES 2022 along with NA300, the world's first sodium-ion solar generator. EP500 is a 100% modular power station exactly like AC300 with an option for adding up extra battery packs for massive storage capacity.
