Hey everyone! I need some advice on picking an inverter/charger for a battery backup system I'm setting up. I'll be working with a 300AH @ 12V battery bank, and I want to make sure I get a reliable unit since it's for critical items in my home. I had my eye on a few options, but with the recent tariffs messing up the prices, I'm reconsidering my choices. Here are the options:
1. Redodo 3000W inverter/charger - priced at $499, it's the cheapest but I'm a bit skeptical about its quality.
2. AIMS 2500W - this one's the priciest at $695, but it has a solid reputation.
3. Victron 2000/12 (open box) - it's the lowest output at $65, but many people say it's top-notch quality.
Based on these options, which one would you recommend?

I'd say go with the AIMS if you can swing the price. It’s more expensive but known for durability, especially if you're relying on this for critical systems. The Redodo is a gamble—might save money but risk more downtime if it underperforms.
Honestly, I'd lean towards the Victron if you're looking for quality. They might not have the highest power, but they're well-regarded in terms of reliability. Just remember that 12V isn't great for loads over 1.5kW; you might need thicker wires. What are your actual peak demands?
Have you considered switching to a 24 or 48V system instead? A higher voltage can be much more efficient particularly if you're pushing close to 2000W. If you want to future-proof your setup, check out options like the Growatt 3000 with 24V batteries. It could save you a lot of hassle down the line!
For my setup, I'm planning for 1800W at peak, but just for backup. I'll use 1/0 welding wire too. Anyone think that's sufficient?
