I'm looking to establish a reliable battery backup system for my home to keep power flowing during outages, especially with the option to charge it using solar power for extended outages. I've learned from Will Prowse's YouTube channel and read his book, but I want to keep things simple for now. My initial plan was to create a more complex setup that integrates with my home power panel, but that seems overwhelming at the moment. I'm considering the following products for a straightforward solar battery system: 2x SOK 48V 100AH Pro Batteries, 1x EG4 3000EHV 48V All In One Inverter, and 4x Hyundai 405W Panels (Voc 45.6). The EG4 inverter requires a minimum of 120V VOC, so I'd wire the panels in series and run the batteries in parallel. I'm hoping for feedback on the reliability and ease of use of these products. Will Prowse recommends this setup, but I'm aware the solar market is vast and I want to make sure I'm making a solid choice that won't require constant maintenance. Any thoughts?

The EG4 is high-frequency, so I’d be cautious about its long-term reliability. You might want to check out Victron products—they’re known for their durability and performance, especially from their marine background. If reliability is what you’re after, they might be your best bet. Just a heads up, many modern inverters are high-frequency, but Victron is often hailed as the best for robustness.
I own the EG4 3000EHV and while it’s done alright for me—like powering a 14,000 BTU A/C in the summer—I don’t think it’s worth the price tag. You might wanna consider going for a cheaper unit, like an Eco-Worthy combo on eBay, which sometimes comes bundled with batteries for a much lower cost. If you can, stretching your budget for the 6000XP could be a good idea, as it outperforms two 3000EHV units and would save you money in the long run.
