Fortress Power + VSUN 450W Plug-and-Play Solar PV System Kit

Complete Hybrid Energy Storage Solution with Smart Monitoring and Extended Warranty

Bring reliable, renewable power home with this complete Fortress Power and VSUN hybrid solar package — a professionally matched, plug-and-play system engineered for simplicity, performance, and long-term durability. Perfect for homeowners, farms, and small commercial sites looking for energy independence, backup power, and utility-bill reduction in one streamlined setup.

How These Work Together

This system combines the VSUN 450 W Bifacial TOPCon solar panels, the Fortress Power Envy True 12 kW Hybrid Inverter, and Fortress Power eForce 9.6 kWh Stackable Batteries — all connected through the Fortress Guardian Gateway for smart monitoring and extended protection.

• VSUN 450 W Panels capture sunlight efficiently from both sides using bifacial TOPCon cells, producing up to 16.2 kW of clean DC power.
• The Fortress Envy 12 kW Hybrid Inverter converts this energy to AC power for your home while managing charging and discharging to the battery bank.
• The eForce 9.6 kWh Batteries store excess energy for nighttime use or grid outages. They can be stacked for up to 57.6 kWh total capacity.
• The Guardian Gateway enables live monitoring, remote diagnostics, and participation in Virtual Power Plant (VPP) programs where available — and when connected, it extends your battery warranty from 10 years to 15 years.

Together, these components create a seamless plug-and-play hybrid PV system designed for fast installation and long-term scalability — whether you start small or go fully off-grid.

Key Technology

High-Efficiency Bifacial TOPCon Modules
VSUN’s advanced N-Type technology boosts efficiency up to 22.5 percent and performs exceptionally well in low-light and high-temperature conditions. Dual-glass construction enhances strength and longevity with minimal degradation.

All-in-One Hybrid Inverter (Fortress Envy True 12 kW)
Provides 12 kW continuous output with up to 21 kW PV input across three MPPTs. The inverter seamlessly transitions between grid, battery, and solar power, supports generator input, and can be AC-coupled for retrofit systems.

Stackable Outdoor Battery (Fortress eForce 9.6 kWh)
Features 48 V LiFePO₄ chemistry, built-in BMS, and outdoor-rated IP65 protection. Units can be paralleled for up to six batteries (57.6 kWh total). Smart temperature management and an integrated heater ensure reliable cold-weather operation.

Guardian Gateway Monitoring
Provides cloud-based energy management for system monitoring, firmware updates, and performance insights. Enables a 15-year extended battery warranty and grants access to grid-service programs such as VPP participation where available.
