Hello,
I am working on a project for a Power Plant that requires a DC+UPS system like the one in the picture below
The two redundant battery chargers as well as the two inverters are a 'customer requirement', but it remains 'open to interpretation' if two STS (Static-Transfer-Switches) + two By-pass transformers + 2 MBS (Manual By-pass Switch) are required.
I think that perhaps using one bypass transformer with a three-inputs STS is perhaps a simpler solution, but I'm not sure if there are three-inputs STS available in the market, and the cost it may have.
I would like to know your opinion!
Best regards,
JBC
