How the Growatt WIT 15kW-HU3-Phase works
Growatt WIT 15kW-HU3-Phase operates in hybrid mode: it stores surplus PV energy in a low-voltage (LV) battery and, when the grid fails, automatically switches key circuits to the emergency power supply (EPS). The generator input and the smart load function let you build a flexible system even where the grid is unstable.
Growatt WIT 15kW-HU3-Phase 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.
A quem se destina este inversor
- Instalações trifásicas com armazenamento de energia — residências, empresas, explorações agrícolas.

Baterias e acessórios compatíveis
Growatt WIT 15kW-HU3-Phase works with low-voltage (LV) batteries: AXE 5.0L-C1, HOPE 14.3L-A1, HOPE 16LM-A1. Backup power is provided by the built-in EPS (backup) module. 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 WIT 15kW-HU3-Phase 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 WIT 15kW-HU3-Phase
The more PV energy you use on site, the lower your electricity bills. As a hybrid inverter, Growatt WIT 15kW-HU3-Phase 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.
WIT 15kW-HU3-Phase parameters in practice
A wide MPPT operating voltage range (150-850 V) makes string sizing easier and lets the installation start producing even in weaker sunlight. The permitted PV array power of up to 24.0 kWp leaves headroom for DC-side oversizing, which increases annual energy yield. High maximum efficiency (97.6%) means lower conversion losses and lower electricity bills.
The inverter comes in an IP66 enclosure, operates across a temperature range of -30°C … +60°C (>45°C derating), uses smart air cooling cooling, weighs 43 kg (dimensions 475×698×240 mm), runs quietly (≈≤50 (4-15K) / ≤55 (17-25K) dB). It is suitable for indoor and outdoor installation.
Instalação e funcionamento
Growatt WIT 15kW-HU3-Phase 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 WIT 15kW-HU3-Phase
The WIT-HU series comprises three-phase hybrid inverters with an LV battery, generator input, black start and parallel operation — a platform for larger residential, agricultural and commercial installations.
What to check when selecting the Growatt WIT 15kW-HU3-Phase
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 WIT 15kW-HU3-Phase 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 WIT 15kW-HU3-Phase
Growatt WIT 15kW-HU3-Phase 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 WIT 15kW-HU3-Phase work with energy storage?
Yes — it is a hybrid inverter, ready for a low-voltage (LV) battery. Compatible models: AXE 5.0L-C1, HOPE 14.3L-A1, HOPE 16LM-A1.
How many phases and MPPT trackers does the WIT 15kW-HU3-Phase 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 WIT 15kW-HU3-Phase 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 WIT 15kW-HU3-Phase 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 WIT 15kW-HU3-Phase provide emergency power during a grid outage?
