Title: interesting new "demo board" - 12V solar to 400V + Post by: Opcom on December 06, 2011, 11:46:19 AM I swear I am not plugging this product, but it is pretty interesting, making up to 430VDC off a low voltage solar panel.
Just thinking about 2 panels, 2 boards in series, and that it might actually run a classic '100W' tube transmitter and receiver. I guess this would work best in the bright sun of the sumertime. High and Low B+. - ultimate bragging - Yes, OM, Here we are using a Viking I and NC-300, totally on solar power..

Roger, KB1CMR does this all the time :-) He is completely off-grid (and has been for many years). He uses a lot of solar, charging batteries and using an efficient inverter. The receiver is solid state, and Roger turns the filaments way down when receiving. He would be a good candidate for a class E rig ;D Title: Re: interesting new "demo board" - 12V solar to 400V + Post by: DMOD on December 07, 2011, 12:06:00 AM Quote for a new photovoltaic panel configuration able to increase the panel energy produced and to simplify the photovoltaic field design and implementation. Maybe a boost inverter to increase DC voltages but not energy.
