TOTEM TWO · T220
More energy.
A clear identity.
20.07 kWh. Integrated heating. A separate hybrid inverter. A system that can grow with your home.
Explore Totem Two ↗THE TOTEM SYSTEM
The power to
think bigger.
Totem combines a separate Core hybrid inverter with floor-standing Two batteries. It uses the same smart meter, Green Balance dongle and Green Hero app as Infinity. Power ratings, battery limits and installation requirements differ between the systems.
Backup power · Core 10
The grid stops. Your essentials carry on.
Core 10 has a separate 10 kW BACK-UP/EPS output and a specified transfer time below 10 ms. Selected loads can be supplied during an outage when the battery, protection and distribution board are prepared for backup operation.
You choose what keeps power.
Lighting, refrigeration and other essential loads can have their own backup group. Core has a separate EPS output, so those loads can remain powered when the grid supply is lost. Available battery power and state of charge determine which loads can run and for how long.

See the connection principle in the Core manual ↗Expansion · two battery connections
Start here. Leave room for more.
Core 10 provides two battery inputs with separate battery management, allowing expansion and different battery banks on separate ports. Battery selection, BMS profiles and connections are agreed with the installer.
Green: power flow. Dashed: BMS communication. Principle illustration, not terminal wiring instructions.
Build capacity at your own pace.
Core 10 provides two battery connections. Two battery banks can be managed through BMS1 and BMS2 according to the selected configuration, allowing the installer to plan for current energy needs and future expansion.
Core 10: 30–60 V DC and up to 105 A per battery connection. The approved battery configuration, communication profile and supplied cable assembly govern the connections.
See battery connections in the Core manual ↗Nano Meter · mini-CT
Small in the cabinet. Central to the system.
Nano Meter with mini-CT measures power flow at the grid connection. The readings help Green Balance coordinate generation, consumption, charging and export limitation.
The same smart meter as Infinity. Three current sensors, one per phase.
- 01
Measure where power flows.
Mini-CT sensors on the three phases measure power flow at the grid connection. Nano Meter occupies one DIN slot.
- 02
Send the readings to Core.
The meter communicates over RS485 to the Core inverter’s METER connection. Phase assignment and measurement direction are checked during commissioning.
- 03
Let Green Balance coordinate.
Meter readings and electricity prices inform how the home charges, stores, uses and exports energy.
Green Balance · Green Hero app
Hardware at home. Insight in your hand.
The Green Balance dongle connects monitoring, the app and control for self-consumption, electricity prices and peak demand. Grid services require activation, an available service and aggregator approval of the installation. Terms and remuneration vary.
The same dongle. The same app.
From battery charging to your home’s energy.
The Green Balance dongle connects Totem to energy control and the app. Follow generation, consumption and battery status, view electricity prices and plan energy use. It is the same familiar interface as Infinity.
The app screens show demo data. Available features depend on connected equipment and activated services.
Totem Two · integrated heating
Heat where the battery needs it.
Our specially ordered Two battery includes a heater, LiFePO4 cells and an IP65 enclosure. Battery temperature monitoring and the BMS determine when charging is permitted.
Prepared for colder days.
Totem Two T220 includes a heater in our specially ordered configuration. Temperature monitoring and the BMS protect the cells and determine when the battery may be charged.
The battery's base specification permits charging at 0 to +55 °C and discharging at −20 to +60 °C. The heater does not permit charging cold cells outside those limits. Permitted current depends on the supplied BMS and heating function.
Technical data and electrical limits
Battery figures apply to one Totem Two 20 kWh. Inverter figures below apply to Totem Core 10 kW, T-CORE-10. Other Core sizes have their own electrical limits.
| Nominal battery energy and capacity | 20.07 kWh / 392 Ah |
|---|---|
| Nominal voltage and operating range | 51,2 V · 44–58,4 V |
| Recommended charging and discharging | 100 A · ≈ 0,26 C · 5,12 kW DC |
| Maximum battery charging and discharging | 200 A · ≈ 0,51 C · 10,24 kW DC |
| Core 10: battery ports and voltage range | 2 × 105 A · 30–60 V DC |
| Core 10: PV inputs and maximum ratings | 3 MPPT · 18 kWp · 800 V DC |
| Core 10: rated backup and transfer time | 10 kW · < 10 ms |
C-rate is current divided by the battery's 392 Ah capacity. DC power is calculated at nominal 51.2 V, before conversion losses. A 105 A port therefore provides approximately 5.38 kW DC, or 0.27 C for one Two battery. The BMS, temperature, state of charge, cables and inverter can impose lower limits. One battery on one port cannot supply 10 kW AC from the battery alone.
The battery's base specification permits charging at 0 to +55 °C and discharging at −20 to +60 °C. The heater does not permit charging cold cells outside those limits. Permitted current depends on the supplied BMS and heating function.
More stored energy, with a properly sized system
In a practical Green Hero system test we operated 15 parallel-connected batteries on one input. This demonstrates expansion potential; it is not a general installation instruction for every battery model or Core size.
The Two datasheet specifies up to 16 parallel battery units. Bank and port counts, common protection, current sharing and BMS communication must be designed for the selected combination. More kWh provides longer runtime; the Core inverter's power limit still applies.
Totem Core: safety and European grid requirements
The manufacturer lists CE-LVD/EMC, IEC 62109, VDE-AR-N 4105 and EN 50549-1 for the Isuna D series. These relate to the inverter. The battery and Green Balance have their own product documentation.
Swedish grid connection uses the model's connection documentation and the correct country profile. The installer handles advance notification and the network operator's response. Certificates must match the supplied model and hardware; a listing for another Isuna variant does not replace that documentation.
