... I believe he meant 'flooded lead acid', but accidentally left out the 'flooded' part for first two batteries he listed... I know *I* leave out the word...

hi there what is every bodys fascination with pure sine wave invertors when the only equipment that realy need pure sine wave are tellys (some) and pc,s most...
Although it is true that deep cycle batteries have more lead, and are heavier, I'm not comfortable rating a batteries purpose by weight. Certain types of...
In our discussion we are referring to flooded lead acids as found in car batteries (sealed, not deep cycle) or golf cart type batteries (non sealed deep...
Most computer equipment and modern tv's (lcd's and plasma) don't care if it's sine or msw (residential computer UPS units are mostly msw). motors like well...
Notice each of the inverters in the stack have their own battery cables. All they are doing is phasing the inverters for stacked operation. Same point holds. ...
hi there ok steve i was not talking about domestic grade ups,s which are even less reliable than comercial grade units. tellys in this country used the ac wave...
hi there i notice these are not pure sine wave units and claim to run most appliances but still waste energy over direct feed if possible if you read there...
... Hi Derek. I mite be way way and I mean way out here, but I'm stuck for a 24vdc dump load for my charge controller, can I stick a 240vac heat on it to dump...
Hi Peter Yes you can, but you will be dis-appointed with it's lack of dump! Because it's a purely resistive heater we can use Ohm's law on the DC values so we...
Derek, List, I have had it on good authority that certain washing machines are not happy with the raw power that comes from an ST alternator. I suspect it is...
Hi David, Fortunately waste veg oil does not contain sulphur for those of us running on it. My heat exchanger is made of stainless steel however. As my exit ...
... Hi. I'm not Derek, but I have an idea. If you wire in series two 12V automotive halogen lights, you will have your dc dump load. Keep them away from any...

Derek, No offence, but most of what you said regarding AC motors is not accurate. An AC motor, whether synchronous or induction, is, by design, intended to run...
... Hi, the makers say to put 20% on top of charger dumpload, so 60a+20a =80x24vdc =1920w. a lot of wasted, I'de like to put it to good use, say take the chill...
hi there if you use a 1kw electric fire element it will draw aprox 1/100 the wattage at 24volts so it would be good for 10 watts aproximately but if you cut...
Hi Kevin, I am sorry but I have not plotted exhaust temp vs load. I am more a suck it and see kind of bloke really. Apologies tim I did measure it once and Ken...
hi there i agree with you they used to be designed that way. and they where when i was trained but all that has gone by the way side now due to the advent of...
Hi Kevin, I seem to recall that at high load the temp was about 400 deg C at the beginning of the exhaust heat exchanger, and 120 Deg C or so leaving the ...
My fridge and jet pump complained bitterly about msw, and although they ran, there was a marked temperature difference. The microwave sounded like it had "sand...
Hi all, The quality of power from the chinese ST type alternators leaves a little to be desired. I wonder what we could do to improve the quality of output...
Dear Tim As I understand it, many companies make the "ST" alternator. Is there a difference in power quality with power from ST alternators made by different...
Derek, That is not correct, and it has nothing to do with the advent of cheap power electronics. An AC motor is designed to work at some specified input ...
Tim & all - the book available through Utterpower.com- Bill Rogers "Home Power Producers Guide to Electrical Reality" has some VERY interesting, insightful&...
