Choosing a Battery Bank for My 2700W Solar Setup

Asked By SolarFlare77 On

Hey everyone! I'm new to solar energy and just bought 6 450W panels for my newly constructed shop. Now I'm on the lookout for a battery bank and an inverter/regulator for my setup. Can anyone suggest what else I might need to ensure everything runs safely? I want to avoid any potential issues, like fire hazards!

It seems like you might want to consider using LiFePo4 batteries; they’re a safer option compared to regular Li-ion. You should definitely look for a reputable company that offers scalable options, especially if you're just starting out and need something reliable!

That's a good point! I was trying to figure out which brands would be both affordable and reliable. Any suggestions?

The size of your battery bank really depends on your energy needs, the limits of your solar controller, and of course, your budget. Start by calculating the total wattage of everything you plan to power, then add about 25% to that for safety. This will help you decide how much storage capacity you actually need. Also, don't forget to grab a fire extinguisher just in case!

Good call on the extinguisher! Is an ABC type sufficient?

Yep, ABC extinguishers are great. And don't worry too much; LiFePo4 batteries are way safer than older batteries!

For your system, I'd recommend a setup like the EG4 3000EHV or the 6000XP along with either an EG4 or Rich Solar server rack. This type of arrangement is pretty efficient, and you can find some useful installation tips on YouTube for wall-mounted setups!
