Description
The Fidus Battery EU module (FB-L-5.12-EU) delivers 4.86 kWh of usable energy at 95% depth of discharge and up to 100 A. The Fidus Battery Plus (FB-L-16) runs at 100% DoD and handles 180 A charging and 200 A discharging, enough for a mid-size hybrid inverter without paralleling. EU modules combine up to 20 per group and up to 6 groups, for a total of up to 583 kWh, which is already farm or small-plant scale. Without heating the battery operates at −10…+55 °C, while Pro versions with cell heating extend the range to −20…+55 °C and suit unheated rooms and outdoor sites in winter. The C5-M class means resistance to aggressive atmospheres, coastal ones included. Cycle life is 8,000+ cycles with a 15-year service life.
How to choose
For winter installation outside a heated room take the -Pro version, since without heating the operating range starts only at −10 °C. A single 16.08 kWh Plus unit is handier than three EU modules when wall space is tight. For a server rack indoors the 48 V US5000 with IP20 is simpler, and a high-voltage inverter needs Force H3. There are no data on Fidus Max yet.

FAQ
Can Fidus be installed outdoors?
Yes, the housing is IP65 rated with C5-M anti-corrosion protection. For frost below −10 °C you need the Pro version with heating, which works from −20 °C.
How does Fidus Battery Plus differ from Fidus Battery EU?
The Plus stores 16.08 kWh at 100% DoD and handles 180/200 A on charge and discharge. The 5.12 kWh EU module is rated at 100 A and combines into groups of up to 20.
What is the maximum capacity that can be built from Fidus EU modules?
Up to 20 modules per group and up to 6 groups give up to 583 kWh. Such an array needs one or more 48 V inverters of matching power.
What is the cycle life of Fidus batteries?
The rated figures are 8,000+ cycles and a 15-year service life. The line is certified to IEC 62619, IEC 63056 and VDE 2510-50.
