Because the Enphase batteries are so expensive (everyone says this, not me!), a lot of homeowners are doing this weird install of Sol Arks only with AC Coupled Micro inverters. Because Enphase is the most popular micro inverter, a lot of these installs use IQ7s and IQ8s. Additionally, if you max out DC PV, then the only way to add more panels to the Sol Ark is to AC…

Thanks for the input everyone. My system uses optimizers on each panel that communicates with the grid tied inverter which complicates the project and apparently not much works with Solar Edge inverters. I don't even know how the strings are set up and my installer is not much help. The combiner box is mounted on my garage roof under one of the solar panels. If I remove the Solar Edge inverter I will also need to remove the optimizers in order for the panels to work with another inverter. I just want to use my existing system and add batteries so there will be power when the grid is down and use batteries at night during the lighter months of solar production. I do get 1:1 with grid export and I would like to keep that going if possible. With such a large array I am finding it to be rather expensive to add in the batteries and new hybrid inverter(s) to safely handle all the power coming in from the array. I may be forced to look at a stand alone off grid system or just install an inverter that uses AC charging to absorb the solar and charge the batteries acting as UPS for power outages.
