Description
SKANBATT PowerWall 51.2V 120Ah - 6,144kWt
With built-in heating foil so it can be used all year round in cold Nordic countries
Skanbatt PowerWall is a very safe and very good battery solution for houses and cabins.
These modules use LiFePO4 cells of the highest quality to ensure trouble-free use for many years.
LiFePO4 is also the lithium chemistry that is considered to be the absolute safest to use, which we believe is important in houses and cabins where you spend time.
PowerWall from Skanbatt is a "HEAT" model with a built-in heating system that ensures year-round use in cold climates.
The heating system is automatically activated if a sufficiently powerful charging source is used and if the coldest part of the battery is below 0. The power for the heating system is drawn from the charging source, not the battery itself.
Skanbatt PowerWall is perhaps the market's best battery solution for use in Norwegian winter cabins where it can sometimes get very cold.
If you have a WIFI router at your cabin, Skanbatt PowerWall can be monitored from wherever you want. Via our cloud solution (free of charge), you can read all the data you need and have full control over capacity, consumption, charging, cycles, etc.
If you need a larger battery capacity, up to 10 PowerWall units can be seamlessly connected in parallel via the supplied communication cable. The battery can easily communicate with different systems via canbus and report total capacity, voltage, consumption and more. For example, this could be Victron Energy (default) or SunSynk. In addition, there is the option of RS485 connection for certain types of inverters or reading from a PC.
In addition to WIFI monitoring, the module has a very nice and clear display that also gives you all the info you need without connecting to WIFI.
The display provides info on: Voltage, capacity, charge, consumption, SOC, number of discharges and temperature.
NB: Batteries connected to Wifi / Internet can be upgraded with new software over-the-air - which provides continuous new functionality with new upgrades.
Skanbatt PowerWall comes complete with wall brackets and the cables needed for mounting and data cable between the batteries (with the exception of battery cables).
Notes: The battery has a built-in function that allows some charging in freezing temperatures, as well as some charging during heating - e.g. when charging from a generator. This is unique and ingenious, and is controlled automatically! Small charging when the battery is charged from a generator starts when the battery has passed 0 degrees Celsius during heating.
We have our own cable for connecting Skanbatt Powerwall to e.g. Victron Cerbo - it is available here
Specifications:
- Chemistry: LiFePO4
- Nominal voltage: 51,2V
- Rated capacity: 120Ah
- Rated energy: 6,144kWh (100% SoC at 25 degrees Celsius)
- Recommended charging voltage: 56,4V
- Recommended trickle charge voltage: 54,4V
- Max recommended load: 100A
- Recommended charging current: ≤ 55A
- Max in parallel: 14 pcs.
- Communication: CAN bus 250 kbit/s (only) - e.g. to Victron Cerbo GX
- Max short circuit current (3s): 500A
- Max simultaneous consumption: 6144W @ 25 degrees Celsius, 100% SoC
- Weight: approx. 75kg
- M8 terminals
- Main switch
- Temperature range consumption and charging: -20 - 50 degrees Celsius
- Heater consumption: approx. 250W. At an ambient and cell temperature of -5 degrees Celsius, the batteries heat up by approx. 0.237 degrees per minute. At approx. +5 degrees Celsius, the batteries open for full charging power. The heating system remains active until approx. +12 degrees Celsius on the coldest part of the battery.
- For offgrid winter use (e.g. Multiplus), we recommend that the absorption voltage is set to 56.8 volts and the absorption time is set to 2 hours. For autonomous operation with a generator, you can cut the generator charge at e.g. 56-56.8 volts.
- Smallcharge in the cold: The battery will accept some charging below 0 degrees Celsius, and manages this itself based on temperature and charging current.
- For charging from -20 degrees Celsius, it can take up to 2 hours before the battery is warm enough to open for full charging power.
- The cells have a passive (resistive) balancing function. New batteries can take a long time before they will be balanced, this does not affect the use in practice.
- For larger installations, an external shunt should be used (2-3 Powerwalls or more) to ensure accurate reading, as large solutions are unable to read low consumption/charging. This applies to all batteries of this type.
- The lowest amount of power registered by the battery's computer is approx. 5 watts.
- DVCC should not be activated.
- Certifications: EN 61000-6-3:2007+A1:2011+AC:2012, EN IEC 61000-6-1:2019, EN IEC 61000-3-2:2019, EN 61000-3-3:2013+A1:2019
Comes complete with user manual and all technical data!
NB: All batteries (including lead batteries) must be charged up to 100% with a suitable charger before use. This is particularly important for Powerwaller to be installed off-grid, as you may not have access to a good charging source at the installation site. The %SoC indication on the battery may differ when it has been a long time since the last full charge - this is normal with all coulomb counters.
