I'm looking to get a Bluetti EB55 and it says it can accept 12-28V/8A solar charging with 200w max. I'm trying to decide which solar panel to get to charge it. I do not want to pay $500 for the Bluetti 200w solar panel if I can get basically the same performance with a $170 HQST 190w panel as...

Gotcha, that makes total sense. The inverter I'm looking at comes with its own wires to connect to the battery, plus I won't be installing the inverter in the system until I save up and purchase it, the second 200w panel, and another battery...so it sounds like I should be good to use 10 AWG...

Thank you for the reply! I'm planning on using it at first as a mobile 200w emergency backup system for my house right now just to charge phones, laptop, and some smaller 20A power banks and Ryobi 18v tool batteries (I have a 12v DC car charger for them). Later on though I want to be able to...

Looking to build a 12v 400w system with a 40A mppt charge controller similar to Will's recent egg crate system. I'm planning on starting with a 200 watt solar panel and later adding an additional 200w panel so that my system will eventually be 400 watts. I want to go ahead and size all the...

Hey thanks for replying. I get what you are saying about the "consumer" system and that would for sure work for charging up the phones/power banks, but yeah I would need some type of AC inverter or 12v dc cigarette lighter to charge the Ryobi batteries. Charging them is pretty important too...

I want to do something very similar with 1-2 100 watt panels and a 300 watt power station. 1. From my admittedly limited knowledge, you shouldn't need fuses between the panels and the Jackery 300 as long as you configure them so they are within the Jackery's input max voltage limits. They...

Hello all...new guy here from WV, USA. Im looking to build a small emergency backup system that I can morph over time into a more adequate system to power a small weekend getaway cabin, and eventually a fully off-grid home on the same property. Don't have a ton of money or time to throw at it...
