Sol-Ark Integration Guide

B. Program the Batt tab in Battery Setup menu:
Notes:
1) If not installing battery-inverter communication, leave the system running in voltage mode.
2) Some voltage levels can only be programmed with "Use Batt V charged" enabled. Some percentage levels can only be
programmed with "Use batt % charged" enabled. You can ignore system values if they are not programmable.
3) Some inverter settings are not programmable with "BMS Lithium Batt 04" has been enabled. You can ignore system
values if they are not programmable.
4) The eVault is a 9.2kW battery and the Sol-Ark is a 9kW inverter, resulting in a 1:1 ratio per the Fortress minimum
inverter sizing standards. If you have installed more inverters than batteries, disable "BMS Lithium battery 04" and enable
:Use Batt-V based control".
5) If recovering a deep discharge battery, adjust the above charge amps to 10A.
Note: If multiple eVault Classics are used in the system, we suggest using the batteries in the open-loop without using co
("Master"-"1"). In such case, disable "BMS Lithium battery 04" and enable :Use Batt-V based control".
Fortress the eVault to charge/discharge at 185A each when in closed loop communication with the Sol-Ark
inverte. Fortress minimum sizing standards require 1 eVault per Sol-Ark inverter. If recovering a deeply discharged battery
with the Sol-Ark inverter, charge and discharge rates should be limited to 15A until the battery voltage is above 50V.
