A couple of starting questions:
1. Does the Wiseguy inverter accommodate backcharging of a battery from an AC source, as per the AC coupling arrangement suggested in the Ozinverter book?
2. What size and design (toroids, cable type and size, number of windings) would be recommended for my toroid? Images of which are attached below through various stages of building. This has been constructed as per the Ozinverter design to draw 6kW continuously and I'm the first cab off the rank with regards to transformer construction.
I gleaned that Wiseguy suggests 37 uH with lower values giving higher idle current and higher values giving better efficiency under load. I need guidance for the design and/or calculations.
No.1: OD 181 mm, ID 89 mm, width 170 mm, mass 24.6 kg.
No. 2: OD 188 mm, ID 91 mm, width 160 mm, mass 25.1 kg.
(one for myself and one for a friend)
