Hello guys and girls,
Im in the planning stages of setting up a typical off grid solar system with one atypical exception: I would like my inverter/solar power to run through a 150 amp automatic transfer switch or 150 amp contactors which prioritizes using battery bank power first. The idea is to utilize solar as much as possible, and once the inverter shuts down due its low voltage cutoff setting the transfer switch or contactors would automatically switch back to grid power allowing my batteries to charge via solar. Once the battery bank is fully charged the inverter would cut-in and trigger the ATS or connectors to revert back to solar power....
I understand this is not the most economical way to go about solar power so no need to spell out the financial shortcomings of this plan of which there are plenty. My only questions are as follows...
1. Would any generic ATS intended for a generator (baring its rated for the appropriate amperage) be capable of doing this if solar was wired to be the priority? Anyone have any experience with this? If so, what ATS was used?
2. Has anyone used or have thoughts on using two 150 amp contactors to achieve this kind of thing? If so, which ones?
Any and all thoughts are welcome and appreciated. Thanks for your time.
