Been experimenting with a modular setup using the 2400 Pro to power my radio station and some kitchen appliances during outages. I wanted something cleaner than my old mix of cables and lead acid batteries.
So far the cableless stacking is actually pretty nice. I expanded the system to around 4kWh and its much more organized. The UPS function works perfectly... I havent had any reboots on my iMac or radio gear which was my main concern.
Tested it with a microwave and kettle running together and it handled it without tripping. Total cost was significantly lower than the big brand alternatives. I saw some talk about the 2400 Pro's grounding on bulgarian .llc and it seems solid for radio use.
Anyone gone all the way to max expansion? How does the charging behave when you have 3+ units stacked?
