I'm looking to upgrade my existing solar setup to support a hybrid system that includes battery storage. I've got a SolarEdge system with optimizers that I've had installed professionally since 2020. My current inverter is a SolarEdge 7600, but it doesn't support batteries, and I'm aiming for a new inverter that's battery-compatible. I'd like to handle the upgrade myself if possible.
The goal is to find a cost-effective solution that allows my home to use solar power during the day while still having enough battery capacity to keep essential appliances running overnight, like the fridge and freezer. The SolarEdge upgrade seems really pricey—around $14,000 for the new inverter, battery, and other components. Is there a better alternative that could work with my existing setup? Any recommendations on integrated systems that won't break the bank?

Another option you might explore is looking for all-in-one integrated systems that can work directly with your current panels and optimizers, as they often simplify the installation. You can find newer products on the market that might suit your needs without requiring a complete overhaul. Focus on units that provide a good balance between solar production during the day and minimal battery capacity for basic night usage. Reach out to several installers for quotes to see if you can find a more cost-effective solution.
If you're looking to go hybrid, I've heard good things about the EG4 18kpv with a PowerPro battery. It can be AC coupled to your existing setup, which means you integrate it without having to change everything out. You might consider selling your SolarEdge optimizers if you decide to go that route, but I’m not sure how that might affect your output.
Also, ditching the optimizers means your system could be limited by the weakest panel in each string, which is something to think about if you've got panels with varied performance. It would be great if you could clarify what you mean by "AC it in"; it typically involves connecting the new system to your grid-tie setup in a way that makes it work together efficiently.
