Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

GleamBright said Hi, new member here with a DIY off grid solar system in development and construction, reading this post about Dunlite turbines with much interest.

I'm about to acquire a refurbishable model M Dunlite Generator at near scrap value, as per attached images, and am piecing together what needs to be done to restore to runnning order. There is also a spare Model M generator, two 750W generators, and various 3 and 4 hub and blade assemblies in varying states of repair, generally poor. On top of this, I will looking at acquiring an L model 48V unit, with tower, in good condition, soon, but I'll start with the pictured unit. Two main issues:

1. The voltage regulator is missing. I refer to a previous quote on this thread by 'b251367'

"The models L and M have a single field winding which is shunt connected via a voltage regulator. .... I have just developed and built a voltage regulator, very simple and low tech. It is just solid state version of the old mechanical regulator and uses a large diode to prevent reverse current."

2. While resistances will be checked on receipt, the owner tells me it was a 32V unit whereas I am designing a 48V system.

Can I get some guidance on how to proceed to reinstate the voltage regulator and convert to 48V?

Nice to see someone else with an old dunlite. Mine haven’t progressed past sitting in the shed yet!
