DIY LiFePO4 High Capacity Build

[solurge]

Hi, I'm pretty new to the space as I was looking to purchase an ecoflow or bluetti and found out it's way cheaper to DIY. The problem is this seems somewhat complex and time-consuming (not as easy as advertised). I'm seeking to gather a consensus on a build of materials for a portable LiFePO4 system using this battery at the core:

• ECO-WORTHY 12V 280Ah LiFePO4 Lithium Battery, 6000+ Deep Cycles, 3584Wh Energy
• What size solar controller do I need?
• 4,000 watt inverter
• Wiring kit - TBD
• Pelican case
• Touch pad switch panel
• What panels and wiring would I need? (Max charge voltage: 14.6V)

The purpose for the system is I want to have a versatile off-grid system capable of powering a fridge (full-size or mini), electronics, fans, lights, etc. Is a versatile system even possible?

That won't power a full size fridge for very long.

I’d do a quick search for solar hand trucks in the forum.
There’s a few fairly popular set ups that seem to most often feature a 24v or 48v all in one inverter from 3000-5000w and a single accompanying battery.

learn from our mistakes. skip the 12v and go right too 48v
