Hey everyone! I'm diving into my first DIY off-grid solar setup and I need some advice. I've received quotes for a total solar kit that includes: 18 bifacial solar panels (700 W each, totaling 12.6 kW), a 10 kW split-phase hybrid inverter (Kevolt Brand), and some additional components like a PV combiner box and cables, all for about $4,580. For the batteries, I'm looking at two 15 kWh LiFePO4 modules for around $3,080. So, all together, that's roughly $7,660 for everything. Here are my main questions: 1. Is $4.6k a fair price for 12.6 kW of panels and the inverter? 2. Is $1.54k for each 15 kWh battery reasonable? 3. Are there better options available in the U.S. for what I need? Thanks for any tips you have!

I’d be cautious about ordering inverters from Alibaba. If you face problems, support could be tricky since many of us haven't heard of those brands. Batteries and panels seem okay to go with, but don’t forget about the extra costs for racking, wiring, breakers, and disconnects that add up during installation.
Are you sure about the inverter size? 10kW might be pushing it—my 38kW setup gets overloaded at times! Also, consider talking to a U.S. supplier for support—they can really help with the logistics. I recommend checking out Signature Solar for a reliable 12kW option. Plus, I’ve found the guy at NC Solar Electric to be super helpful for DIY setups!
Definitely research the inverter brand! For off-grid systems, reliability is key—you want gear that can last 10+ years. I’m not familiar with that specific brand, but make sure to choose something well-reviewed.
That's solid advice! You want equipment that won't fail when you need it the most.
Before you decide, think about your long-term plans with this setup. Many people in the U.S. prefer to buy batteries from Alibaba but stick to local companies for panels and inverters because of support issues. It might be worth looking into that.
Is there going to be an inspection for this system? If so, start chatting with your local authority about requirements. You might need certified equipment for everything to pass inspection. And don't forget to plan how to mount those big panels—they might require rapid shutdown devices according to code, which can add to your costs too!
Yeah, having someone to guide you through it can save you a lot of headaches later on!
