Description
Output is 220/230/240 V at 50 or 60 Hz with harmonic distortion below 1 %, clean enough for sensitive electronics. A 12 kVA peak for 5 s covers inrush of pumps and refrigeration. Communication is built in, with Wi-Fi, CAN for a lithium battery BMS and RS485 Modbus for external automation, and data goes to the maker's monitoring portal. Charge current is up to 125 A over a 38–68 V window. Grid connection meets EN 50549, Italian CEI 0-21 and Belgian Synergrid C10/11. The IP65 housing, 182 × 439 × 575 mm and 39 kg, can hang in a garage, plant room or under a canopy.
How to choose
The main limit of the next1 is a single phase. For a three-phase supply or more than 6.5 kVA, move to the next3 with 15 kVA continuous and two MPPT inputs. PV connects to the next1 through an external MPPT, for 48 V the VarioTrack VT 80-175 up to 5000 W or the VarioString VS 120 up to 7000 W. Simple off-grid duty without a grid can also go to the Xtender XTM 4000-48.

FAQ
What communication ports does the next1 have?
Wi-Fi, CAN for the BMS link and RS485 Modbus are built in. Monitoring runs through the maker's portal with no separate gateway.
What surge can the next1 deliver?
The inverter delivers 12 kVA for 5 s and 6.5 kVA for 30 minutes, with 4.5 kVA continuous.
Can the next1 be mounted outdoors?
The IP65 housing is sealed against dust and water jets, so a sheltered outdoor spot is fine. Avoid direct sun to keep heat derating down.
Which batteries does the next1 work with?
With 48 V banks in the 38–68 V range and charge current up to 125 A. Lithium batteries connect over CAN so the inverter takes charge limits from the BMS.
