Overview

The ASW3000-S-G2 is a 3kW single-phase string inverter with two independent MPP trackers of 16A, for small arrays split over one or two orientations. Up to 4.5kWp of PV can be connected within a 60–560V MPP range and a 600V input limit; feed-in starts at 100V. Maximum output current is 15A and maximum efficiency 98.2%. The fanless IP66 housing measures 368×325×145mm and weighs 9.5kg, and the model is covered by Solplanet's CEI 0-21 certificate.

  • 3–6kW single-phase, two MPP trackers
  • 600V max. input, 60–560V MPP range
  • 16A per tracker for large-format modules
  • 98.2% max. efficiency, night consumption below 1W
  • 9.5kg, 368×325×145mm, natural convection
  • CEI 0-21 and EN 50549-1 certificates

How it works

The S-G2 converts the power of two independent PV strings into single-phase AC at 220, 230 or 240V. Each tracker accepts 16A (24A short-circuit), the DC input is limited to 600V and MPP tracking works from 60 to 560V with a 360V rated input and a 100V feed-in voltage. The PV array can be oversized, from 4.5kWp on the ASW3000-S-G2 to 9kWp on the ASW6000-S-G2. Maximum efficiency is 98.2% and European efficiency 97.5%.

Installation and compatibility

Weighing 9.5kg and cooled by natural convection, the inverter can be wall mounted indoors or outdoors (IP66, -25…+60°C, up to 4000m). Leave 500mm above and below and 300mm at the sides. Because a residual current monitoring unit is integrated, an external RCD is not required; where local rules demand one, use Type A or Type B rated at least 100mA per inverter. Each inverter needs its own circuit breaker, with no loads between breaker and inverter.

Solplanet publishes a CEI 0-21 certificate covering the ASW1000- to ASW6000-S-G2, an EN 50549-1 certificate, EMC and TÜV mark certificates and an EU declaration of conformity, plus the technical information sheet used for the Italian Regolamento di Esercizio. The global datasheet also lists AS/NZS 4777.2, IEC 62109-1/2, IEC 61727, IEC 62116 and NB/T 32004.

Monitoring and settings

A Wi-Fi stick is supplied for monitoring and configuration in the Solplanet App; LAN is available and 4G is optional. Zero export or export limitation uses an approved single-phase smart meter, such as the SDM230-Modbus, wired to the 2-pin RS485 port; with Wi-Fi stick monitoring, power control applies to a single inverter. The datasheet also lists an optional AC power supply and optional AFCI.

Questions and answers

Is an external RCD needed?

Not by the inverter itself, because a residual current monitoring unit is integrated. If local regulations require one, Solplanet allows Type A or Type B devices tripping at 100mA or more per connected inverter.

Can the S-G2 limit export to the grid?

Yes. With an approved Modbus smart meter such as the SDM230-Modbus on the RS485 port, the inverter limits its feed-in, including zero export; with Wi-Fi stick monitoring this works for one inverter.

Is the S-G2 certified for CEI 0-21?

Yes. Solplanet's CEI 0-21 certificate covers the ASW1000-S-G2 to ASW6000-S-G2, including the ASW3000-S-G2.

How much PV can be connected?

The datasheet allows 4.5kWp on the ASW3000-S-G2, 5.52kWp on the ASW3680-S-G2, 6kWp on the 4kW model, 7.5kWp on the 5kW model and 9kWp on the 6kW model.
