Professional System Design Required
This is not a plug-and-play package. A qualified professional must confirm panel string sizing, racking, conductor sizing, overcurrent protection, grounding, disconnects, battery settings, equipment clearances and all applicable electrical and building-code requirements. Actual solar production, usable battery energy and supported loads depend on location, weather, system settings and operating conditions.
Frequently Asked Questions
Is this kit for off-grid or grid-connected use? +
This package is offered exclusively for off-grid installations and is not intended for utility-interconnected systems.
Is the system output 16kW? +
The solar array is 16.02kW DC. The Envy Duo 21 provides 12kW of continuous AC output and up to 16kW peak output. Solar-array size, continuous inverter output and peak inverter output are different ratings.
How much energy does the battery store? +
The Fortress Power eForce battery system provides 19.2kWh of nominal energy storage.
How long will the 19.2kWh battery run my property? +
Runtime depends on the average electrical load, battery reserve settings and system losses. For example, a 2kW average load will run much longer than central air conditioning, electric heat or other high-demand equipment. A professional load analysis is recommended before purchase.
Can the system be expanded? +
Yes. Envy Duo 21 inverters can be paralleled up to 120kW, and the eForce platform can be expanded up to 153kWh of total storage. Expansion must follow the applicable Fortress Power design and installation requirements.
Is Guardian monitoring included? +
Yes. One Fortress Power Guardian monitoring hub is included free with this kit. It provides system tracking through Wi-Fi or Ethernet connectivity.
Does this kit include everything required for installation? +
No. The package includes the panels, inverter, battery system and Guardian hub listed above. The final installation may require racking, wiring, disconnects, overcurrent protection, grounding equipment and other balance-of-system materials selected for the property.
What warranties are included? +
The Trina Solar panels include a 15-year product warranty and 30-year performance warranty. The Fortress Power Envy Duo 21 inverter and eForce battery each include a 10-year manufacturer warranty, subject to the applicable warranty terms.
