Kommentar eines Experten
“We recommend the Growatt WIT 15kW-HU3-Phase model as a dependable hybrid platform with room to add energy storage. It is a battery-ready design — the low-voltage (LV) battery can be added at any point, without replacing the inverter. When sizing the system, we pay attention to the correct battery voltage class, the number and length of the strings and the correct configuration of the backup supply — we are happy to review your design before purchase.”

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.

Die Wahl des richtigen Energiespeichers
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.
Installation und Betrieb
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.

Häufig gestellte Fragen
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?
Ja. Dank der Schutzart IP66 ist eine Installation im Innen- und Außenbereich möglich. Wir empfehlen einen schattigen Standort, der keiner längeren direkten Sonneneinstrahlung ausgesetzt ist und über WLAN-Empfang für die Überwachung verfügt.
What warranty does the WIT 15kW-HU3-Phase carry?
The product is covered by a European service warranty (10 years per manufacturer).
Kann ich die Installation aus der Ferne überwachen?
Ja, über die ShinePhone-App und das ShineServer-Portal per WLAN – mit einer Übersicht über Produktion, Verbrauch und Akkustatus.
Does the WIT 15kW-HU3-Phase provide emergency power during a grid outage?
Yes — the built-in EPS (backup) module keeps selected circuits supplied when the grid fails.
Was ist der Unterschied zwischen einem Hybrid-Wechselrichter und einem netzgekoppelten Wechselrichter?
Ein netzgekoppelter Wechselrichter speist die gesamte PV-Energie ins Netz und in die Anlage ein, funktioniert jedoch nicht mit einer Batterie. Ein Hybrid-Wechselrichter kann zusätzlich überschüssige Energie in einer Batterie speichern und die Stromversorgung bei einem Netzausfall aufrechterhalten.
Where can I find the full electrical specification of the WIT 15kW-HU3-Phase?
Im offiziellen Datenblatt des Herstellers sind die MPPT-Spannungs- und Strombereiche, der Wirkungsgrad, die Abmessungen und das Gewicht aufgeführt. Die wichtigsten Werte sind in der obigen Spezifikationstabelle zusammengefasst.
