Official 2025 catalogueStuder Innotec selection questions
What output power is available in the Studer NEXT1 range?
The 48 V single-phase range includes the nx1 4500-48, rated at 3.5 kVA continuously, 4.5 kVA for 30 minutes and 10.5 kVA for 5 seconds, and the nx1 6500-48, rated at 4.5 kVA continuously, 6.5 kVA for 30 minutes and 12 kVA for 5 seconds. Up to three NEXT1 units can be configured in parallel, three-phase or split-phase systems.
What output and solar capacity does Studer NEXT3 provide?
NEXT3 is a three-phase 48 V inverter/charger rated at 15 kVA continuously and 16 kVA for 30 minutes. It integrates two independent high-voltage MPPT inputs, each providing up to 8 kW of solar power.
Does Studer offer 19-inch rack integration?
Yes. NEXT3 is available as a dedicated wall-mounted model or 19-inch rack model. NEXT1 is wall-mounted and can be adapted for professional 19-inch rack integration with the Studer nx1 rack plate.
What is the maximum PV open-circuit voltage of VarioString?
The VS-70 accepts a maximum PV open-circuit voltage (Voc) of 600 Vdc. The VS-120 accepts 600 Vdc with its two MPPT inputs operating independently or in parallel, and 900 Vdc when they are connected in series. String Voc at the lowest site temperature must remain below the applicable limit.
What is the difference between VarioTrack and VarioString?
VarioTrack is the low-voltage MPPT range for 12, 24 or 48 V batteries, with maximum PV Voc of 145 or 175 Vdc depending on the model. VarioString is intended for high-voltage PV strings and 48 V batteries, with up to 900 Vdc Voc and 7 kW recommended PV power on the VS-120.
Can SINES Export ship Studer equipment worldwide?
Yes. SINES Export supplies professional projects and coordinates air or sea export logistics according to destination and order.
