I installed a HUGE (at least for my boat) Maxwell HWC2200 windlass
. I engineered my system to operate on 24vdc. The very last thing I want to happen is for a 12vdc battery
to go belly up while hauling in my 88# Delta
along with 200' of 5/16"HT chain. OK, so I have a dedicated 24 system but in reality, mine is not so dedicated. Also, because we run our 7.5KW generator
every morning for coffee along with battery charging
and again at night to ensure hot water
is available and also operate the stove and chargers, our inverter
keeps the 24v bank at full charge.
I purchased a 24vdc Freedom 1500 inverter/charger on Ebay for $250 bucks. NOTE--- 24V SYSTEM CAN BE LESS EXPENSIVE IF YOU SEARCH EBAY!!! Most inverters along with chargers are the popular 12v boxes, the demand for 24v on Ebay is no where near as great as for the 12's. NOw I am not in love with the old Freedoms but for $250, I could not go wrong.
I use the inverter
to power my TV, microwave, low energy 120vac lamps and other miscellaneous power loads. I use two each group 29 12v batteries in series and have NEVER had a problem with them since I installed the system 4 years ago.
Remember---- P= (I^2)*R
for equal watts at 12v is twice that needed for 24v. BUT THE WIRING
LOSSES WILL BE 4 TIMES AS MUCH!!! Think about it.
I highly recommend the higher voltage system. If I could have purchased a 48vdc windlass
or for that matter, one that operated on 120vac, I would have purchased it.
