Our community has rated this post as helpful. If you agree, why not thank pricesniper

At this price point, if you don't need the portability, I would recommend buying an all-in-one inverter like the 6000XP connected to LifePower 48V batteries. It's eligible for the 30% solar tax credit, UL listed, and if a battery degrades or needs to be swapped, you don't need to send the entire unit to a company like Ecoflow.

If you do need portability, check out Will Prowse's Solar Kart series on YouTube.

no thanks. 6000xp fan noise is quite loud and annoying. only suitable for installing away from living area. also, much more difficult to set up. if you want something diy, at least recommend the flex boss, which is much quieter than that screaming hair dryer 6000xp.
