My experiences? I have the EB240 and AC200P. Used mainly as alternative power for the computer room. Large computer PSUs generate surges in power and neither handles this well, the AC200P being better at this. I previously had surge limiters for some old amps, so these solve the issue.
ACP200P has a higher output current rating, but a smaller battery. I like both of them, if it was not for the fans in the external PSU blocks. These units need to be put in the garage/basement or the other side of the office as I have them. I believe this is a common problem unless you pay a lot of money for the PSU.
The AC200P has more advanced software, but neither have any sort of app or way of reading or controlling charge. The AC200P comes with dual charging, but only one charger, and even if you buy another charger, you still need another adapter. The AC200P adapter works with the EB240 and is a much better option than the 230w one they supply in the box.
As for the charge level shown on the AC200P, seems to me it's a bit erratic. Turning off and on can produce a different percentage. The lack of ability to use as a UPS is also a major pain. Finally neither have a bypass circuit, so if you charge and power something, it's always going via the battery. A lot of UPSs will draw the AC directly, and use the spare to charge the battery. Less cycles, more efficient.
