The manufacturer next3 — three-phase hybrid inverter-charger 16 kVA with MPPT
Country: Switzerland · Model: next3
Three-phase hybrid inverter-charger next3, rated 15 kVA continuous and 16 kVA for half an hour, with two built-in MPPT trackers and a 48 V battery bus. It serves off-grid and grid-tied PV plants with batteries where one unit works with the grid, a generator and the solar array at once.

Description
The output is three-phase 380/400/415 V, or 220/230/240 V per phase, at 50 or 60 Hz. With solar generation it peaks at 30 kVA for 5 s, enough to start pumps and compressors. Each PV input takes 8 kW at up to 900 V open-circuit, so long strings need no external controllers. Charge current reaches 300 A, or 15 kW, within a 36–68 V DC window. The AC flex input takes a second source such as a generator, or a dedicated load. Efficiency is 97 % on the solar→grid path and 95 % on solar→battery. Grid connection follows EN 50549-1:2019 and VDE-AR-N 4105:2018, with tests to IEC 62116 and IEC 61727. The IP20 enclosure, 320 × 450 × 760 mm and 58 kg, goes indoors on a wall or frame rated for that weight.
How to choose
The choice comes down to three phases and a 48 V battery. If the site is single-phase and 6.5 kVA is enough, look at the next1 (nx1 6500-48) in an IP65 enclosure. For cabinet mounting the same inverter comes as the next3 rack at 8U height, and a ready cabinet with up to 31.8 kWh of batteries is sold as infra. Existing Xtender sites can stay with the XTH at 3000–8000 VA, paralleled into three phases.

FAQ
What battery works with the next3?
A 48 V DC battery, the inverter accepting 36–68 V. Charge current reaches 300 A, so size the bank and its BMS for it.
How much PV can be connected to the next3?
Two MPPT inputs of 8 kW, 16 kW in total, with string Voc up to 900 V. Panel count follows from module Voc at the lowest site temperature.
Can the next3 be connected to the grid in the EU?
Yes, the inverter meets EN 50549-1:2019 and VDE-AR-N 4105:2018, and anti-islanding is tested to IEC 62116.
Can the next3 be installed outdoors?
No, the IP20 rating is meant for a dry indoor room. For damp locations the range has the next1 in an IP65 enclosure.
