WernerMy batteries I am using at present are private labled Trojans, although I have used Trojans in the past, these are the same batteries in a different case, at a cheaper price.I believe a company called Douglas makes most of the North American batteries, then supplies different cases for different customers who want their name on the batteries.There is a huge range to their product line, I have been told.I don't care who's name is on the case, I just want the heavy plates, with lots of area. I really hope I can get a self generating system working before I need to buy new batteries.Cheers Warren

HI WARREN As far as batterys are concerned you are using TROJANS . Well I use trojans on my solar systemand they are OLD GOLF CART BATTERYS I get them bring them home & set up my capacitor charging/restoring unit& run the battery(one at a time) up tyo 15.5 volts & leave it there for a couple of hours. After I'M done restoringI fill up the water to good level &use the batterys for 4 to 5 years .when they get to old I go get more USED TROJANS
The used trojans are $35ea.plus $35 core charge a lot cheaper than NEW!
JUST A THOUGHT!!

Hi Sven In the case of the boat, which sits at a mooring most of the time, the solar cells do the charging.Under sail, at any speed over 2 knots, 17 amps of 14 volt dc is available from the rotating propeller shaft, from the boat travelling through the water.A big dc motor is belted off the propeller shaft, with a single blocking diode.When the 85hp John Deere engine is on, there are two alternators, a 105 amp Delco and a 120 amp Leaseneville..
The big golf cart batteries are 6 volts each 225 amps.So what I do is put them in pairs, from new, and consider them as 12 batteries in two manageable modules. I then have the 12 volt modules in parallel, giving what I call "the house power" a total of 450 amps.In addition, I carry two more six volt golf cart batteries in a separate circuit for engine starting, operating the electric clutch to the hydraulic system, and engine related operations. Either system can be linked together for any purposes, giving 700 amps of 12 volt dc,£ which has never been needed.Generally, those two 40 watt panels do a terrific job with their charging controllers keeping the battery banks at 13.8 volts all the time.Those 40 kg each, battery must be replaced every 6 years, at a rough cost of $1.00 per amp.I hate using batteries.Cheers Warren

I would have to reprocess the energy of the pushpull transformer first into a capacitor and then use it to operate a classic buck converter and would again have an impedance problem if the capacitor is charged too much and the impedance increases too much.
I think I will agree with the seller. The Variac can provide 23 ampere continuous load and 30 ampere for a short time. The peak voltage is 300V. The winding can also be connected so that the full impedance can be directly connected without a slider. So it would be a toroidal coil with a very high inductance with a very low ohmic resistance, interesting for many nice experiments.
If really one ignites a mega EMP these are the only devices that could regulate a voltage for resourceful electricians.
Your batteries are your only supply?
4x 6V batteries in series? as a 24V unit?
How many ampere hours does a battery have?
Do you still charge them with the Rene Charger and the few solar cells?
How big is a set of 40W solar cells in watts of final output?
regards
Sven
