In my signature is my installation using an Outback Skybox. My suggestion is that you decide what capacities you need in terms of surge capacity, if any, kW maximum consumption needed to cover times when you are using a lot of electricity. How much solar panel capacity in kW do you have with your existing 36 panels? Finally how much battery capacity do you need in kWhs?
Then you can look at hybrids that fit your specs. If you do not know these answers there are several links to energy audits where you can come up with a reasonable estimate. Hybrid inverters come in various sizes and prices. You can spend $10,000 or you can find some basic hybrids for a lot less. There are lots of threads talking about various hybid inverters that could work well with your existing system of micros.
