## Overview

Engineered for residential and small commercial solar installations, this compact micro inverter delivers reliable power conversion with impressive 96.4% maximum efficiency. The unit handles up to 800 watts of AC power output while maintaining consistent performance across varying weather conditions, thanks to its robust IP67 weatherproof rating that protects against dust and water ingress.

What sets this inverter apart is its dual MPPT channel design, allowing each channel to handle up to 18 amperes of DC input current independently. This configuration maximizes energy harvest from paired solar panels by optimizing power point tracking for each module separately. The single-phase output makes it ideal for standard residential grid connections, while the micro inverter architecture enables module-level monitoring and reduces system-wide performance losses from shading or panel mismatch issues.

## Frequently asked questions

### What size solar setup does the GoodWe MIS suit?

The GoodWe MIS is rated at 800 W nominal AC power, with the same 800 W listed as its maximum, making it one of the smallest units in GoodWe's range rather than a whole-home inverter. It is single-phase, so it fits an ordinary domestic circuit, and its output scale points to a one- or two-panel installation rather than a full rooftop array.

### How many MPPT inputs does the GoodWe MIS have?

The GoodWe MIS has 2 MPPT channels, each rated for up to 18 A of DC input current. At only 800 W total output, that pairing is enough to give two small panels or two differently angled modules independent tracking, which is the point of a unit built for panel-level rather than whole-array power conversion.

### How efficient is the GoodWe MIS?

The GoodWe MIS reaches 96.4 percent maximum efficiency. That is respectable for a unit operating at only 800 W, though it trails the 98-99 percent figures typical of larger string inverters, since efficiency curves tend to flatten out at higher power. Expect a slightly larger share of the panel's output lost to conversion than on a full-size string system.

### What kind of inverter is the GoodWe MIS?

The GoodWe MIS is categorized by GoodWe as a compact, module-level microinverter rather than a central string inverter, which fits its tiny 800 W output and dual independent MPPT inputs. Its enclosure carries an IP67 rating, meaning it can handle temporary immersion as well as dust, which matters since micro-inverters typically mount right behind or under the panel outdoors.

### What grid connection does the GoodWe MIS need?

The GoodWe MIS is a single-phase inverter, so it connects to an ordinary domestic circuit rather than requiring three-phase service. Given its 800 W maximum output, it is designed to sit at the panel level as part of a distributed microinverter system, with several units combining on one circuit rather than a single central inverter handling a whole roof.
