Fortress Power Inverter Product Types

Fortress Power offers a range of inverter options to suit different energy needs and system configurations. Let's explore the main product types that we offer at Solar Guys Pro:

Hybrid Inverters

Hybrid inverters, like the Fortress Power Envy series, are versatile solutions that can handle both grid-tied and off-grid applications. They allow you to store excess solar energy in batteries for later use, provide backup power during outages, and even sell surplus electricity back to the grid. With features like built-in generator inputs and AC/DC coupling, hybrid inverters offer unparalleled flexibility. 

Off-Grid Inverters

For those looking to go completely off-grid, Fortress Power offers dedicated off-grid inverters. These inverters are designed to work seamlessly with battery storage systems, enabling you to power your home independently from the utility grid. With robust surge protection and high continuous power output, off-grid inverters ensure reliable electricity supply in remote locations or during extended power outages.

Grid-Tie Inverters

If your primary goal is to reduce your reliance on the grid and lower your electricity bills, grid-tie inverters are the way to go. These inverters directly feed the solar power generated by your panels into your home's electrical system, offsetting your energy consumption from the grid. Fortress Power's grid-tie inverters boast high efficiency ratings and easy installation, making them an excellent choice for grid-connected solar systems.

How to Choose the Right Fortress Power Inverter

Selecting the perfect Fortress Power inverter depends on your specific energy needs and system setup. Here are some real-life scenarios to help guide your decision:

• Hybrid Inverter: If you want the flexibility to store solar energy for later use and maintain power during outages, a hybrid inverter like the Fortress Power Envy series is ideal. These inverters seamlessly integrate with batteries, allowing you to create a comprehensive energy storage solution.

• Off-grid inverter: For those living in remote areas without access to the grid, an off-grid inverter is essential. Fortress Power's off-grid inverters are built to handle the demands of standalone solar systems, providing reliable power day and night.

• Grid-tie inverter: If your primary objective is to reduce your electricity bills and contribute to a greener future, a grid-tie inverter is the simplest and most cost-effective option. These inverters maximize the energy you send back to the grid, earning you credits on your utility bills.

No matter which Fortress Power inverter you choose, you can be assured that you're investing in a high-quality, reliable product backed by exceptional customer support.

FAQs 

Q: What battery bank sizes does Fortress Power offer?

Ans: Fortress Power offers the 18.5kWh eVault MAX, which comes as a single unit, and the modular 5.4kWh eFlex. The eVault MAX is scalable up to 220kWh, while the eFlex can be scaled up to 81kWh.

Q: What inverters are compatible with Fortress Power batteries? 

Ans: Fortress Power batteries are compatible with most 48V inverters, including those from Outback, Schneider, Sol-Ark, Magnum, SMA, and Victron. As long as the inverter's DC input is 48V, it should work with Fortress batteries.

Q: What battery chemistry do Fortress Power batteries use?

Ans: Fortress Power batteries use the safest type of lithium chemistry - Lithium Iron Phosphate (LiFePO4). This chemistry requires no cooling or ventilation and delivers 6,000 cycles at 80% depth of discharge.

Q: How long is the warranty on Fortress Power batteries?

Ans: Fortress Power batteries come with an industry-leading 10-year warranty, demonstrating their confidence in the longevity and performance of their products.

Q: Do Fortress Power batteries have a Battery Management System (BMS)?

Ans: Yes, Fortress batteries have a powerful embedded BMS that can close-loop communicate with inverters. The BMS can handle large charge/discharge currents and enables remote monitoring.

Q: What type of battery cells does Fortress Power use?

Ans: Fortress Power uses prismatic cells, which are more robust, efficient, and thermally stable compared to the cylindrical cells used by competitors like Tesla and Simpliphi. Prismatic cells also offer a longer lifespan.

Q: How do Fortress Power batteries compare to lead-acid or AGM batteries?

Ans: Fortress Power lithium batteries last 6 times longer than lead-acid or AGM batteries, require 1/6th the space, and have 1/3rd the energy cost over their lifespan. They are designed to last 15 years.

Q: Can Fortress Power batteries provide whole-home backup power?

Ans: Yes, but the duration depends on the loads and inverter. For example, an 18.5kWh eVault MAX can power a 3kW load for 6 hours without recharging. Proper sizing is important for whole-home backup.

Q: Are Fortress Power batteries suitable for off-grid applications? 

Ans: Absolutely. Fortress Power batteries are designed for various applications, including off-grid, backup power, self-supply, peak shaving, and more. They can be AC or DC coupled with solar PV systems.

Q: What operating temperature range can Fortress Power batteries handle?

Ans: The eFlex can operate from 50°F to 95°F without derating. Below 50°F, charging is limited, and the battery will shut off around 20°F to prevent damage. For cold climates, a DIN rail heater is recommended.
