Q: What is the Battery Voltage?
A: The battery outputs 48V with a with an operating voltage range of 48V ~ 57.6V, with a nominal voltage of 51.2V.
Q: Can the EI Battery be used with other inverters?
A: No. Unfortunately, the EI Battery can only be used in conjunction 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 EI Battery is ground-mounted only. It features two integrated anti-tip brackets to secure it to the wall.
Q: Can I use a different battery with Tigo's EI Inverter?
A: Tigo strongly recommends that all components in an EI system are manufactured by Tigo. However, there is a limited pairing option that can happen, when using as an AC Battery (only).

Q: What is the EI Battery’s SOC (%) at complete discharge?
A: When completely discharged, the EI Battery’s State of Charge (SOC) is 10% of the battery’s absolute capacity.
Q: Does the EI Battery hold charge enough to dark start?
A: Yes, when completely discharged the EI Battery still reserves enough charge (SOC of 10%) to start back up.
Q: How many battery extension cabinets can be added to the EI system?
A: Currently, up to two EI batteries can be connected together for a total capacity of 19.8 kWh.
Q: Is there a BMS in each EI Battery cabinet or in each EI Inverter?
A: The battery management system (BMS) is integrated into the EI Battery.
Q: How many battery modules are in each EI battery cabinet?
A: There are 3 battery modules in each EI battery cabinet.
Q: How is the battery system monitored?
A: The battery is monitored by the EI Platform, either online or on the Tigo App.
Q: Does the EI Battery charge to a full 100%?
A: Yes.
Q: Does the EI Battery degrade faster being a full 100%?
A: The battery will autonomously cycle charge to prevent accelerated degradation depending on the mode of operation selected by the user. Regardless of the mode selected by the user, the EI Battery will reserve enough charge (SOC of 10%) to start back up when necessary.
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 enter standby mode, to protect all its components for future use.
