The latest Goodwe 20kW 3-Phase Hybrid Solar Inverter price in Pakistan is Rs. 735,000/- updated on October 20, 2026.
The Goodwe 20kW 3-Phase Hybrid Solar Inverter runs your home on solar, battery and grid power. It belongs to the GoodWe ET LV Series (5–20kW), a three-phase hybrid range for residential PV systems. The model number is GW20K-ET-L-G10.
Overview
The ET LV Series works seamlessly with low-voltage (48V) batteries. This model offers real flexibility, because it supports a wide range of battery capacities and brands. These include GoodWe’s own Lynx A G3, Lynx U G3 and BAT 14kWh low-voltage batteries. As a result, it gives homeowners a reliable and scalable energy storage solution.
The inverter has 4 independent MPPT trackers and 2 battery inputs. It also suits on-grid, on-grid plus backup, and generator-assisted operation.
Reliable Backup Power, Always Ready
The ET LV switches to backup power in under 4 milliseconds. So essential household loads stay powered without any noticeable interruption, even during a grid outage. The inverter is also fully compatible with generators. In fact, it can draw on generator power to recharge the connected battery bank. This adds energy security during long outages, cloudy periods or emergencies when solar alone isn’t enough.
High Performance for Demanding Energy Needs
- Each MPPT string accepts up to 20A of input current
- Supports up to 2x PV input oversizing (200%) relative to the nominal rating
- Installers can therefore connect a larger array and capture more usable energy across the day
- Extra panels help especially in low-light or partially shaded conditions
- Dual independent battery inputs on the higher-capacity models deliver a combined total of up to 416A
- Greater throughput also gives more flexibility when sizing storage for high-demand homes or future expansion
Smart Control and Monitoring
Beyond fast backup switching and generator integration, the ET LV supports remote monitoring and configuration. You can use GoodWe’s SEMS Portal and SolarGo App for this. Homeowners and installers then see system performance, battery state of charge and grid interaction in real time. In addition, installers can push firmware updates remotely.
Safety and Reliability
An optional AI-driven AFCI (Arc Fault Circuit Interrupter, version 3.0) continuously scans the DC side for arc faults. Arc faults are a leading cause of PV system fires. When the AFCI detects a fault, it disconnects automatically. Then it restores operation once conditions are safe. Type II surge protection devices (SPD) also sit on both the DC and AC sides. They guard against voltage transients from lightning or grid switching events.
More about the Goodwe 20kW 3-Phase Hybrid Solar Inverter
The enclosure carries an IP66 ingress protection rating. So it is fully dust-tight and resists powerful water jets from any direction. This makes it equally suitable for indoor or outdoor installation. Furthermore, an anti-corrosion C4 rating extends its suitability to coastal and humid environments.
Flexible and Adaptable Applications
The ET LV Series works with both Li-Ion (LFP/LiFePO4) and lead-acid battery chemistries. It is also compatible with GoodWe’s Lynx A G3, Lynx U G3 and BAT 14kWh low-voltage battery lines. As a result, homeowners have several ways to size their storage now and expand it later.
The Goodwe 20kW 3-Phase inverter also supports unbalanced output of up to 150% across phases. This helps in homes where the load is not evenly spread across the three phases. That is a common real-world situation, and many inverters in this class don’t handle it as gracefully.
