Yes, when the bank is sized to your unit. A 16,000 BTU marine unit draws about 11 amps at 120 V once it is running, with a short surge at start. We size for that load plus a margin, then show you the math.
The systemWith one A/C on a four-battery bank, 8 to 14 hours. Set it to medium on a cooler night and it runs longer. Need more? We add batteries. You get your number in writing.
Fridge, lights, TV, and outlets, along with the A/C. We add those loads to your sizing sheet. [Cooktop and water heater pending.]

We use LiFePO4, a stable lithium chemistry. A battery management system watches every cell. Every install follows ABYC E-13, and you get the paperwork.
Safety standardMost insurers ask for proof of a standard install. You get a wiring diagram, a component list, and installer sign-off. [Insurer list pending.]

Cost comparisonA yearly check of connections and firmware. No oil, filters, or impellers.
