Since you have racks of computer equipment and have designed your own UPS, you know that the devil is in the details. Before buying any equipment, it would be a good idea to put your entire design on paper to make sure you have everything specified and to see if the design meets your goals. Battery and/or hybrid inverters often cost quite a bit more than standard grid tied inverters.
For me, I have net metering and had to declare my equipment set before my net metering connection was approved. If I change the intent of my original equipment set (like adding another inverter and/or more solar panels, or a battery), I have to go back to the power company for approval with limited exceptions. If you have net metering, you might be in the same situation.
Reading some of your other posts, you have a system that the installer has left you hanging, microinverters that have been obsoleted with virtually no support from Sunpower, do not have installer access to the SunBridge Monitor and possibly have some microinverter failures. I know you bought some microinverter replacements on eBay, but can you install them without installer access to the SunBridge Monitor?
For me, your SunBridge episodes above would drive me crazy. At this point, I would be trying to find out how to salvage as much as I could from my original system and design that into the new and improved battery/hybrid inverter system. You said you didn't have any shade so a string inverter would work fine. If you wanted panel monitoring and/or had some shade, you could put in Tigo TS4-A-O optimizers. I have an SMA string inverter with installer level access that can be used standalone without a continuous internet connection.
Anyway, there are many options out there.
