Inverter

[Tom Warner]

Bill I believe you may have amp hours confused with watts. Your
batteries are rated in amp hours for example T105s are 225 amp hours
and not watts. you use a coffee maker for 10 minutes it may
consume 1500 watts or about 250 amp hours. And remember their is a
discrepancy as far as batteries and alternators. Batteries put out
approximately 13.2 vdc while alternators are rated at 14.2 volts
