I have my 8 foot single rotor & a 4 foot single rotor up , both are 12 volt mills.
I put a heavier tail on the 8 foot to see how high I could go before burn out.
Usually I get peaks of 20 amps with the 4 foot on the silo & 35 on the 8 foot(down low to the ground).
Last night my inverter was shutting down from the batteries going past 15.2 volts & the needled stayed right at 80 amps in the house(both mills joined)for 1/2 hour with the odd peg at 90.
When I get everything rewound for 48 volt I will go with new batteries, it seems most my power is used to keep the batteries up , when I have 80 amps coming in & the batteries are almost charged , at 15 volts- 1200 watts I only need to pull 300 - 400 watts off & the batteries will drop dramatically.I have a huge used lift truck bank but i taken care of it poorly , when it is charged fully , a 30 amp draw will drop it down to 12 volts almost immediately , a low draw say 10 amps will last forever it seems , I figure it is very sulfated......
Can't wait to be able to afford a new run of trojan's to see more effeciency...
I was looking at a 48 volt grid tie inverter that charges batteries as well , I will post it here later maybe some of you have tried it & I can get some feed back.
She's blowing hard again today.
