I'm trying to set up a reliable power backup at my home in the suburbs for both short and long-term outages. Right now, I have a Jackery 1000V2 paired with a 200W folding solar panel and a small dual fuel inverter generator that mainly charges the Jackery on cloudy days. My focus is on keeping my chest freezer running, along with some lights, a fan, and charging phones. I'm okay forgoing a TV or microwave during an outage.
Initially, I thought about buying a second Jackery, but I've become interested in a DIY solar solution. I've just purchased 4 x 100W Renogy solar panels, and I understand I need a solar charge controller, a battery, and a power inverter.
I'm looking at 12V 100Ah LifePo4 lithium batteries priced around $150 each. Are these suitable for my setup, and is the price fair? I'd like recommendations for a compatible solar charge controller and power inverter that can work with my 4 panels and eventually allow for adding more batteries. Additionally, should I worry about the batteries not being used for long periods? I'm open to any advice or corrections if I'm off track. Cheers!

It sounds like you're on the right track! Starting with monitoring your energy consumption is a smart move. Consider investing in some smart outlets to help gauge what devices you need to support during power outages. This will give you a clearer idea of your power requirements moving forward. Just remember, balance between quality and cost is key—don't skimp too much or you might regret it later!
You might want to keep an eye out for combined systems that can grow with you. Investing in a quality charge controller and inverter now will save you money down the line. Also, the price for LifePo4 is about right! Look at common brands to ensure reliability. And you can always add more batteries later for increased capacity—just make sure they’re compatible with your existing setup. Just keep everything maintained properly to prevent issues from long periods of inactivity.
For a solid solar charge controller, look for a MPPT (Maximum Power Point Tracking) model, as it optimizes your energy collection efficiency. Brands like Victron or Renogy have good options. As for the power inverter, you’ll want a pure sine wave inverter that can handle the wattage of your appliances. It’s great to hear you want to expand your battery setup! Lithium batteries are fantastic—just make sure to check their compatibility and maintenance needs. About battery storage, keeping them at room temperature and charged is important, especially if they're idle for long periods. You can use a low voltage disconnect to help with that too!
