Hey everyone! I currently have an Enphase solar lease that's working pretty well for me, but I'm looking to add battery backup. The catch is that I'm not an installer and don't have installer access. Since my system is AC coupled, I'm considering getting another grid-tie inverter and a DC battery system. My question is, how do I configure the settings on the inverter without installer access? Will I be able to program it myself, or is that not possible? I'm using around 1.5 kW at peak during the day and producing 5 kW, so instead of selling back to the grid, I'd like to store that energy in batteries for use at night. I'm eyeing the Growatt 10k grid-tie inverter or the EG4 grid boss, and I'm looking to build a battery bank of around 30 kW. Plus, I'm planning to expand my property, so I want to make sure I integrate this into the main house rather than adding a second solar system.

You don’t need to touch your existing Enphase system if you’re not using their batteries. Just make sure that the battery inverter you choose is compatible with AC coupling. A crucial point for backup systems is ensuring you have a plan for grid disconnection and knowing which loads will still run when the grid goes down.
I think the Growatt 10k Grid-Tie Inverter looks really promising! Here’s a link to check it out: [Growatt 10kw Grid Tie Inverter](https://www.portable-sun.com/products/growatt-10kw-grid-tie-inverter-min10000tl-xh-us). Definitely worth considering for your setup.
If you haven’t yet, I suggest checking out the free online courses on Enphase University! They’re pretty straightforward, and getting installer access could really help. As for batteries and inverters, you’ll want to do some research to find the best fit for your setup. I recently snagged some Enphase batteries for under $2K each, and I found them super easy to install, sticking with the Enphase ecosystem can make things simpler.
That sounds intriguing! Where did you find those batteries? I'd love to look into it.
Yeah! I'm with you on that. It's more about not pulling from the grid at night than keeping everything powered during an outage.
