Look into the Magnum inverters as 2nd chargers, very good chargers with
generators.
I have done this many times, in the case of failure of the other inverters
for some reason, run wires and be back up and running.
I think the 4448 inverter is 60 amps @ 48 volts with an input of 16 or so
amps A
I use and have used [1] 48 volt-15 amp or [2] 24 vdc - 25 or
40 amp IOTA chargers in series for 48 vdc @ more than15 amps
for years with great results. They take really poor quality
power and put out just fine, and are super efficient as in
great watts per gallon of dead dinosaur burned.
Thanks
Hello, Benn~
As regards Iota: these deliver a constant voltage...in fact they strongly
resemble a DC power supply. A "45 amp" Iota type charger would deliver that
rated amperage only so long as the battery voltage is low relative to the
charger's output. In my experience these type chargers taper
HI All,
Say I've had a question from a client about AM radio noise from his
battery-less inverter.
I'm wondering if there is any other folks out there who have found this to be
problem?
Now I realize that most people listen to AM in the evening when the inverters
are non-op so this might not
G'day Wrenches,
I'm looking for an additional charger(s) to increase the charging capacity
from the back-up 12 kW Onan generator into the 1200 Ah battery. Right now the
generator's full potential output is limited by the charging capacity of the
two VFX3648's which have a max charge output of

Thanks all for the good feedback. A service upgrade to this flush mount

I'm in agreement with Brian on this one. Of course, the realities are that it's
another big expense associated with putting in a system and doing a service

Another option is to install a gutter between the meter and the zinsco

Using a separate J-box is key. Even better (and cleaner) than Polaris are
NSI distribution blocks in your J-box. The inspector will appreciate the

Jeff,
This is any easy one.
REPLACE THAT ZINSCO SERVICE PANEL!!!
That is just a fire waiting to happen. I wouldn't touch it with a 10'pole.
There are all kinds of horror stories all over the internet about Zinsco panels
causing fires. There is a reason why they are no longer in business.

The Lorentz pump may be the ticket. Due to stratification, surface
pumps will not correct the situation in this 10 acre lake.
Thank you Mark and all other responders.

Thanks for the input Jeff. This is a basic small Meter/Main (100A) only. The
feeder leaves the main and runs about 200' to the house. Removing the short
jumper leads from the meter socket and routing them to another panel and then
back again to the Main seems like far more modification to the pa
Jeff's idea is good, but I think the only potential violation of the listing of
the service panel, would be if you drilled and tapped into the buss bar.
Tapping the cable w/ a listed connector shouldn't cause any trouble to the
service panel. (230.33 specifically allows the service cable splice
Right! So long as the tap isn't made inside the box, it can't have any
effect on the listing of the box.

If possible, install a j-box between the meter and MSP, run the service
entrance conductors through it unbroken and through Polaris type
connectors for the tap.

Larry, for a while in the 80's Zomewworks offered a small DC bubbler to keep
ice from skimming over livestock tanks. This was a standard aquarium air
pump with a tiny diaphragm. I think it was a very good idea and worked well,
but for a larger pond, I am certain I've seen this application before. T
