Off-Grid Power Services: Marine, RV, Cabin & Backup
System design and wiring diagrams, lithium upgrades, charging, monitoring, battery backup, parts and technical support – from a team with more than 50 years of combined experience.
Lithium Upgrades for Boats, RVs and Cabins
Cruising boats and yachts, RVs, hunting cabins, tiny houses, remote cameras, even high-end portable restrooms for exclusive events: Access Power has built DC power systems for all of them. Our power professionals design the system around how you actually use it.
Battery Backup and Portable Power
We design efficient battery backup, whether you are starting fresh or replacing an existing bank, including backup power for data centers and other critical sites. We also build portable power: EV charging stations, power for traffic signs and light towers, and camping setups. And we can turn a generator-only system into a hybrid that runs the generator far less and saves fuel.
Remote System Monitoring
Is downtime costing you money? Know what is happening across your boats, vehicles or remote sites. We set up easy-to-use monitoring that shows location, temperature, battery state of charge and the power coming in and going out, so you catch maintenance issues before they become expensive.
High Output Alternators, DC Electric Motors, and Smart Regulators
Custom High Output Alternators and Smart Regulators are no joke. There is a ton of disinformation out there. Let us help you dial in your Boat, RV, or Specialty Vehicle with the appropriate charging system. Whether you’re taking a World cruise on your new yacht, or heading out to a national park for the next month, we can help dial in your charging system.
Thruster Motors, and Windlass Motor testing, Repair, and Preventive Maintenance solutions are also a service offered by Access Power. These critical parts are extremely important to your user experience. Let our Power Professionals help you if you are in doubt.
