Client Type: Mobile Home / RV Owner
System Installed: Fortress Power eForce 9.6 kWh Battery + ENVY 8kW Inverter
Application: Complete Off-Grid RV Power System
🚧 The Challenge: Off-Grid Living in a Remote Area
For a mobile homeowner in Aguas Buenas, going completely off-grid wasn’t just a lifestyle choice—it was a necessity.
No Grid Access: The RV site has no access to LUMA utility power.
Indoor Installation Limits: Many popular solar battery brands are restricted from being installed in occupied indoor spaces, making them unsuitable for RV use.
Full Energy Independence: The client needed a reliable, compact, and safe solar battery for RVs that could deliver autonomous energy 24/7.
🔋 The Solution: Fortress Power Battery + ENVY Inverter
To meet the client's off-grid goals, the integrator selected:
1 × Fortress Power eForce 9.6 kWh Battery
1 × Fortress Power ENVY 8kW Inverter
This DC-coupled solar battery system was installed inside the trailer, providing a safe and compact footprint using lithium iron phosphate (LFP) battery technology—ideal for enclosed living spaces.
The system is fully functional without grid power and is future-ready for solar panel or generator integration, offering total energy flexibility.
