Three-phase output

Three-Phase Power. Flexible Living.

Rated 12 kW on a three-phase 220/380 V or 230/400 V supply. 100% unbalanced output lets each phase deliver up to 50% of rated power, so uneven household or small commercial loads do not have to be balanced by hand.

Total output stays within the inverter’s limits. The result is three-phase power that still follows how the building actually uses electricity.

  • 12 kW rated AC
  • 100% unbalanced output
  • 50% per phase, max.
  • 3-phase 220/380, 230/400 V
Built for Outdoor Conditions

Outdoor enclosure

Built for Outdoor Conditions

IP65 means the cabinet is dust-tight and protected against water jets, so it can be mounted outdoors. Operating temperature is −40°C to +60°C.

Power derates above 45°C. Plan the install for that temperature range, and expect reduced output once the air around the inverter climbs past the derating point.

  • IP65 ingress
  • −40°C lower limit
  • +60°C upper limit
  • >45°C derating
Energy on Your Schedule

Six periods

Energy on Your Schedule

Six configurable battery charge and discharge periods. Set them around the tariff and the way the site uses power through the day.

Where peak and off-peak prices apply, charging can sit in the cheaper windows and discharge can cover the expensive ones. The schedule follows the routine you set, not a single fixed cycle.

  • 6 charge / discharge periods
  • Tariff and daily use
Expand with Your Energy Needs

Parallel expansion

Expand with Your Energy Needs

Up to 10 inverters in parallel, both on-grid and off-grid. Multiple batteries can run in parallel on the storage side.

Start with one inverter and add units as the site’s demand grows, without changing the basic three-phase, low-voltage layout.

  • 10 max. parallel units
  • On-grid and off-grid
  • Batteries in parallel
More Ways to Keep Power Available

Backup and generator

More Ways to Keep Power Available

Diesel generator energy can be stored, so a generator is another path into the battery, not only a direct backup source. Off-grid peak is 2× rated power for 10 seconds.

That short peak is for load starts. It is subject to system and battery limits, and it does not raise the continuous rating.

  • 2× off-grid peak
  • 10 s peak duration
  • Generator energy storage
Give Existing Solar a Storage Upgrade

Existing solar

Give Existing Solar a Storage Upgrade

AC coupling adds battery storage to a compatible existing PV system. The present array can stay in place while storage is added on the AC side.

How the inverter is tied in depends on the system design. The point of the retrofit is storage, not a full replacement of the solar already on the roof.

  • AC couple retrofit storage
  • Existing PV can stay
Two MPPTs. Flexible Solar Design.

Roof layout

Two MPPTs. Flexible Solar Design.

Two independent MPPT trackers and three PV strings (2+1). Max. operating PV input current is 26 A + 13 A, so one tracker can take a larger array than the other.

MPPT voltage range is 200–650 V. Different roof faces can be tracked separately instead of being forced onto one string voltage.

  • 2 MPPT trackers
  • 2+1 PV strings
  • 26 A + 13 A operating current
  • 200–650 V MPPT range
Low-Voltage Storage. Powerful Charging.

Charge and discharge

Low-Voltage Storage. Powerful Charging.

A 48 V battery connects through transformer isolation on the battery side. Max. charge and discharge is 240 A.

Battery voltage is 40–60 V, lead-acid or lithium. Usable current follows the battery and its BMS. Multiple batteries can run in parallel.

  • 240 A max. charge / discharge
  • 40–60 V battery range
  • 48 V battery system
  • Isolated battery side
