Q: What is the Battery Voltage?
A: Nominal battery system voltage to the EI Inverter is 400V. However, internally, the battery modules operate at 48V.
Q: Can the EI Battery be used with other inverters?
A: No. The EI Battery can only be used with Tigo Inverters.
Q: What is the elevation rating on the EI Battery?
A: The elevation range of the EI Battery is 3000 meters (9842 feet).
Q: How is the EI Battery mounted?
A: The default mounting method for the EI Battery is ground-mounted. It features two integrated anti-tip brackets to secure it to the wall. However, this Help Center article shows how to wall mount the battery cabinet using a prepared list of materials. Wall Mounting the Tigo EI Battery
Q: Can I use a different battery with Tigo's EI Inverter?
A: Tigo strongly recommends that all components in an EI system be manufactured by Tigo. However, when using it as an AC battery (only), there is a limited pairing option.

Q: What is the EI Battery’s SOC (%) at complete discharge?
A: At 10% SOC, the EI Battery will enter standby mode. The EI system is still powered and waiting for a charging source (PV, grid, generator). Once the SOC drops to 7%, the system enters sleep mode and shuts down to prevent a deep discharge. Once in this state, you must perform a dark start.
Q: Does the EI Battery hold charge enough to dark start?
A: Yes, when the system has entered sleep mode, the EI Battery still reserves enough charge to start back up. However, you should only perform a dark start when sufficient PV is available for battery charging. Repeated dark starts without a charging source will cause the battery to enter a deep discharge and become unrecoverable.
Q: How many battery extension cabinets can be added to the EI system?
A: Currently, up to four EI batteries (two strings of two) can be connected for a total capacity of 38.6 kWh.
Q: Where is the EI Battery battery management system?
A: The battery management system (BMS) is integrated into the EI Battery cabinet.
Q: How many battery modules are in each EI battery cabinet?
A: There are three 3.3kWh battery modules in each EI battery cabinet. The EI Battery cabinet always ships with three battery modules.
Q: How is the battery system monitored?
A: The Tigo Energy Intelligence (EI) Platform monitors the entire energy storage sytem, either online or on the Tigo App.
Q: Do you have a system sizing tool?
A: Tigo offers an online Battery Sizing Tool that can help you make the right decision for your energy needs. You may also gather datasheets and manuals from our Downloads section, or even reach out to our Sales Engineering Team for complimentary assistance in sizing and designing your system.
Q: What happens to the battery if the load is exceeded?
A: If the loads try to pull more than the 5000W continuous or the 6000W maximum capacities, the EI Battery will automatically shut down to protect all its components for future use. You must manually restart the battery.
