The Fortress Power Avalon Battery Management System - AV-BMS is essential for the safe and smart operation of Avalon energy storage stacks. Designed for advanced lithium stacks, it acts as the system’s brain. It constantly monitors, balances, and safeguards each battery module. Whether in residential or commercial setups, the AV-BMS guarantees long-term safety and durability.
Designed for precision, the Fortress Avalon BMS module 1 per Battery Stack is vital for every Avalon stack. It optimizes energy handling to maintain consistent performance.
Fortress Avalon BMS module functions as the “brain” of the high-voltage stack. It handles cell monitoring, pack protection, and communication. This top-mounted device offers quick installation and includes a DC breaker, power button, status LED, and ports such as BMU, Heater, COM, and P+/P− power bus.
With factory-integrated control plus communication cables (BMS→SEP & BMS→Inverter), the Fortress Avalon BMS module supports stacks of 3–6 battery modules (AV-B). [installation guide]
| System role | Controls and protects Avalon high voltage stack; interfaces with inverter & Smart Energy Panel (SEP) |
|---|---|
| Compatibility | Stacks of 3–6 AV-B modules (14.7/19.6/24.5/29.4 kWh) |
| Communication | CAN bus to SEP & Hybrid Inverter; BMU chain to modules |
| On-board interfaces | POWER button · DC breaker · P+ / P− power · COM (CAN) · BMU · HT heater · PE ground |
| Included cables | BMS→SEP comm cable (24 V + CAN) · BMS→Inverter comm cable (supplied) |
| Stack electrical (ref.) | Nominal current 50 A; voltages 144–288 V depending on 3–6 modules |
| Ingress protection | IP65 (stack rating) |
| Operating temp. (stack) | Charge −10 to 50 °C · Discharge −20 to 55 °C |
| Warranty (stack) | Battery limited warranty up to 15 years (see system docs) |
Installers benefit from the Fortress Avalon BMS module with plug-and-play control, ensuring safer operation, solid communication, and quick commissioning. It fits cleanly in UL9540 setups with Avalon ESS.
This system tracks battery health, voltage balance, temperature, and communication between modules and inverter. It monitors each cell’s condition in real time to prevent overcharge, deep discharge, overheating, and faults.
Proper balancing of battery stacks improves efficiency and extends lifespan. The AV-BMS works seamlessly with compatible system setups for smarter energy storage and enhanced safety.
Each Avalon battery stack requires a dedicated unit to manage safety and efficiency. The Fortress Avalon Battery Management System 1 per Battery Stack - Avalon BMS Module - AV-BMS assures consistent power and safe operation.

This is the first stage of my three planned purches. I got the eg4 inverter 6000 XP base kit with six 400 watt panels and the two server rack batteries. Did a little online research and followed the instructions and it got set up without any issues. Right now I'm just running it in my garage on a single outlet and have been running dual 750 watt water distillers with it. Once I get the second inverter and a bunch more panels and batteries, I plan on attaching it to my subpanel in my house that has my lights and outlets and appliances on it. Then I'll get a soft start for my AC and blower and run it on my main panel.

Trying to pick the correct solar system for your needs can be very technical and frustrating. I wanted to thank Yvhan and the Portlandia Electric supply team for their patience and helpful attitudes through multiple calls. I feel like we were able to narrow it down to what worked for me and my family. My system works great and I couldn't be happier to have picked Portlandia Electric Supply.

I wanted to get an offgrid solar system for years but didn’t know where to start. I found Portlandia Electric Supply on Facebook and decided to submit a quote. Within 24 hours I had a custom proposal that was almost half the price of the companies I had previously got quotes from. My wife and I decided to order online and the kit came in a timely manner and it was an easy install. Great company to work with!
James Martin
I would like to take the time to express the outstanding service that I was provided with by Portlandia Electric Supply. They provided me with all the answers to my questions, and after reviewing our quote over the phone I felt comfortable proceeding to order my kit. It’s exactly what I needed and they were there to help us over the phone when we had questions installing it. I highly recommend others in need to choose Portlandia Electric Supply.

As a professional videographer, I needed reliable power on the go.Portlandia Electric Supply Delta Pro and roof-mounted panels were the perfect solution. Setup was easy, and the kit included everything needed. The Delta Pro powers my cameras, lights, laptop, and a small fridge with impressive battery capacity.

You folks have been wonderful guiding me through the ins and outs of going solar. Plus your tech guys Rod and Nelson are the absolute best. They explained all the different aspects of inverters, batteries and how to keep them in top condition. Too much more to put here… but no other company has the 100% tech support you provide for your customers!

My experience with Portlandia Electric Supply has been excellent. Before the sales, they answered all my questions to assure that I got what I needed. After the sales they continued to support me with answers and help. I had a warranty issue with a unit, and it was handled as well as possible. I would recommend them to anyone looking to go solar.
