I recently received a quote for a Tesla Powerwall 3 with AC coupling and backup, totaling around $18K, which is meant to supplement my existing paid-off 7.75kWh setup. I'm looking for better DIY options with my electrician, so I would appreciate any guidance or recommendations. Help me out, community!

You might want to check out the EG4 battery lineup. They offer some solid options that could work for your needs. For instance, look up the EG4 FlexBoss21 model—it’s a good choice for a DIY setup!

Consider going for a hybrid inverter like the EG4 18kpv or Sol Ark 15k. These come with wiring diagrams on their websites, making installation easier. Just remember, you might need some extra parts like a disconnect or bypass. I'm currently looking into DIY batteries myself, and I found the DIY Solar Forum really helpful for tips and knowledge.
The EG4 WallMount Indoor Battery is a great option. It’s 48V with 280Ah and 14.3kWh of capacity. Plus, it has a heated feature and a 10-year warranty, and you can often find it for about $3,700. After adding an EG4 inverter, you should still come in well under your $18K quote.
