Safe distance between two energy storage inverters

In most cases, it’s recommended to keep the distance under 100 feet (30 meters). But ideally, it’s best to keep the distance between 20 to 50 feet. Why? Well, it’s all about efficiency. [pdf]

FAQs about Safe distance between two energy storage inverters

How far apart should inverters and batteries be in a box?

A few ppl have commented about things like batteries being 5 feet apart or front/rear clearance required for panels, inverters, etc.. All of this does away with those videos of inverters and batteries in a box together. But as I said, I go by Code. So when Im told x, I look for it or ask to tell me what ordinance.

How far away should a storage battery be from a consumer unit?

My electrician insisted that the storage battery we have - Growatt B3-Alpha and an additional battery module should be no more than 2-4 meters away from consumer unit. Is this reasonable? We have a flat roof extension to place the panels and loft recess next wall to it on 2nd floor. The consumer unit is on ground floor.

Can I use a 240 volt inverter with a 150 volt battery?

Yep 150' , but you'll need cable as thick as your forearm lol If you need to share battery storage between two systems, your best bet would be to find some way of AC coupling between the two inverters, and send the juice between them in 240-volt AC. Higher voltage=smaller wires and lower voltage drop.

Should batteries be kept close to a DC inverter?

The numbers will be huge. I'd recommend keeping the batteries close the the inverter. Your costs would be astronomical for appropriately sized DC lines of that length. Efficiency would also suffer. Just have two separately located battery banks if you require battery support for both inverters.

Should I buy an inverter or a battery?

For all the work and expense of trenching that, and losing up to 6-7% of your power along the way, you’re waaay better off just buying a battery or two (with the added benefit of increased capacity). Btw, if you AC coupled those inverters, you’d be looking at only 8 AWG to get 6,000 watts from one site to the other at 120/240 volts.

Can a battery inverter be used as a conductor?

Edit: Well, technically you *can* do it, if you want to spend a fortune on conductor. Go to a wire ampacity chart and voltage drop calculator, and plug in the numbers for 48 volt and whatever battery amps you’re trying to run, and the 150 foot distance. The numbers will be huge. I'd recommend keeping the batteries close the the inverter.
