How the Growatt MID 20KTL3-XH works
Growatt MID 20KTL3-XH is a three-phase battery-ready inverter with a backup function. It runs in grid-tied mode from day one, and the HV energy storage (APX 5.0P-B1) can be added later — without replacing the unit.
Growatt MID 20KTL3-XH has 2 independent MPPT trackers, which lets you connect strings of different orientations and lengths and maintain a high yield even with partial roof shading. You follow the installation in real time in the ShinePhone app and the ShineServer portal — with fault alarms and production history.

Baterias e acessórios compatíveis
Growatt MID 20KTL3-XH works with high-voltage (HV) batteries: APX 5.0P-B1 (HV). The set is completed with the APX 98034-P2 control module. Backup power is provided by the SYN-100-XH-30 back-up box EU. Browse the full energy storage range in our shop — we will help you match storage capacity to your consumption and installation size.
Escolher o sistema de armazenamento de energia adequado
Storage capacity is matched to daily energy consumption and the goal of the investment: to increase self-consumption, storage covering the evening load is usually enough, while genuine backup power calls for more capacity and discharge power. Growatt MID 20KTL3-XH lets you expand the storage in stages — start with one module and add more as your needs grow. Write to us at info@growatt.tech and we will size the storage for your installation.
Self-consumption and savings with the Growatt MID 20KTL3-XH
The more PV energy you use on site, the lower your electricity bills. As a hybrid inverter, Growatt MID 20KTL3-XH stores surplus energy from the panels in the battery and releases it in the evening instead of exporting it to the grid. Self-consumption rises, bills fall and the payback period of the installation shortens — and during a grid outage you still have an emergency power supply for key circuits.
MID 20KTL3-XH parameters in practice
A wide MPPT operating voltage range (160-1000 V) makes string sizing easier and lets the installation start producing even in weaker sunlight. The permitted PV array power of up to 40 kWp leaves headroom for DC-side oversizing, which increases annual energy yield. High maximum efficiency (98.75%) means lower conversion losses and lower electricity bills.
The inverter comes in an IP66 enclosure, operates across a temperature range of -25…+60°C, uses smart air cooling cooling, weighs 31 kg (dimensions 580×435×230 mm). It is suitable for indoor and outdoor installation.
Instalação e funcionamento
Growatt MID 20KTL3-XH is three-phase (230/400 V) and has an IP66 enclosure, so it can be mounted indoors and outdoors. Installation should be carried out by a qualified installer in line with the manufacturer’s manual and the local grid connection requirements. Once commissioned, the inverter reports to the ShinePhone app and the ShineServer portal — you get a remote view of production, consumption and the battery state of charge. The unit is covered by a European service warranty (10 years per manufacturer).

What sets the series apart — Growatt MID 20KTL3-XH
The MID TL3-XH series comprises commercial three-phase hybrids in an IP66 enclosure — for commercial installations focused on self-consumption with an energy storage option.
What to check when selecting the Growatt MID 20KTL3-XH
When buying an inverter, the key is matching its power rating to the panel power and distributing the modules correctly across the MPPT trackers. Growatt MID 20KTL3-XH is three-phase (230/400 V) and has 2 independent MPPT trackers, so it pays to plan the number and length of the strings around the available operating voltages already at the design stage. If you are considering energy storage, pay attention to the correct battery voltage class and the compatible models listed above — a battery from the wrong class rules out the expansion. It is also worth planning the mounting location in advance (ventilation, Wi-Fi access for monitoring). If in doubt, send us your design — we will verify the selection free of charge before purchase.
Monitoring and the app — Growatt MID 20KTL3-XH
Growatt MID 20KTL3-XH works with the free ShinePhone app and the ShineServer portal. Once the inverter is connected to a Wi-Fi network, you get a constant remote view of energy production, current consumption, the battery state of charge and the history for any period. The app sends notifications about faults and drops in production, so the installer or the owner can react to issues quickly. For installers managing multiple sites, Growatt provides service accounts with a view of the whole inverter fleet from a single panel — convenient for maintaining installations across many customers. Remote monitoring also simplifies warranty handling: operating data makes diagnosis easier without a site visit.

Perguntas frequentes
Does the Growatt MID 20KTL3-XH work with energy storage?
Yes — it is a hybrid inverter, ready for a high-voltage (HV) battery. Compatible models: APX 5.0P-B1 (HV).
How many phases and MPPT trackers does the MID 20KTL3-XH have?
The inverter is three-phase (230/400 V) and has 2 independent MPPT trackers. The number of MPPT trackers determines how many independent panel groups you can connect — important for roofs with differently oriented surfaces.
Can the Growatt MID 20KTL3-XH be installed outdoors?
Sim. A classificação de proteção IP66 permite a instalação tanto em ambientes interiores como exteriores. Recomendamos um local à sombra, longe da exposição prolongada à luz solar direta, com cobertura Wi-Fi para monitorização.
What warranty does the MID 20KTL3-XH carry?
The product is covered by a European service warranty (10 years per manufacturer).
Posso monitorizar a instalação remotamente?
Sim, através da aplicação ShinePhone e do portal ShineServer por Wi-Fi — com uma visão geral da produção, do consumo e do estado da bateria.
Does the MID 20KTL3-XH provide emergency power during a grid outage?
Yes — the SYN-100-XH-30 back-up box EU keeps selected circuits supplied when the grid fails.
Qual é a diferença entre um inversor híbrido e um inversor ligado à rede?
Um inversor ligado à rede alimenta toda a energia fotovoltaica à rede e à instalação, mas não funciona com uma bateria. Um inversor híbrido permite, além disso, armazenar o excedente de energia numa bateria e manter o fornecimento de energia durante uma falha na rede.
Where can I find the full electrical specification of the MID 20KTL3-XH?
Na ficha técnica oficial do fabricante — são indicados os intervalos de tensão e corrente do MPPT, a eficiência, as dimensões e o peso. Os valores mais importantes estão resumidos na tabela de especificações acima.
