Fortress Power - Victron Inverter Guide
Step 9 – Updating firmware (optional):
All Fortress batteries are now shipping with firmware necessary for closed-loop communication with
Victron inverters. While firmware updates are not something an end user should regularly perform,
installers get in the habit of bringing the Fortress firmware update tool and Windows laptop to site
during any site visit to update battery firmware and access detailed battery information that can speed
up commissioning and diagnostics. Do not update battery firmware while the battery is under load.
Fortress installers should request a firmware update tool at https://www.fortresspower.com/support by
filling out a support ticket. End users and installers who have not filled out the dealer form may
purchase the tool for ~$50 by filling out the support ticket.
Visit https://www.fortresspower.com/firmware for instructions.
Step 10 – Operating in Voltage Based Control (for
paralleled eVault Classics):
The eVault Classic BMS is not capable of BMS control. Voltage
controls can actually be more accurate when the battery is near
full or near empty – there is little if any real function difference
between running in %-based BMS control or voltage based
control. Use this chart to approximate battery voltage and state of
charge for “Grid Limiter” settings. Also, change the float and
absorption charge to 54.4V instead of 56V.
