SolaX Power: Hybrid inverters, batteries and connected energy controls

SolaX Power supplies solar and hybrid inverters, storage batteries and controls that coordinate generation, charging and flexible household loads.

Summary

Best for
Homes and smaller commercial sites coordinating solar, batteries, EV charging and heat pumps.
Less suited to
Treating an RJ45-shaped communications connector as an Ethernet port without its pinout.
Deployment
Inverters and compatible batteries, with optional DataHub, EV charger or heat-pump adapter.
Data in
Inverter and site information through documented RS485 connections and SolaXCloud.
Pricing
Equipment and installation require supplier quotes; software terms depend on the selected service.

Overview

SolaX Power develops photovoltaic and storage equipment, combining inverters and batteries with monitoring and energy controls. Its catalogue extends the system beyond generation to vehicle charging and other flexible electrical loads. This makes the company relevant to buyers who want solar, storage and consumption to work together within one installation. The useful engineering question is which device coordinates each function: the inverter manages electrical conversion, while products such as DataHub and the heat-pump adapter add site-level connections. Those roles differ from simply displaying solar generation in an app.

Offering

The X3-ULTRA family is a three-phase hybrid inverter range with 15 kW, 19.9 kW, 20 kW, 25 kW and 30 kW variants. SolaX describes parallel operation and separate photovoltaic, grid and backup-side specifications. Its product tables also distinguish MPPT configurations by exact variant, including differences between standard and P models. This matters for installations with several roof orientations or larger arrays: the family name alone does not settle the input arrangement. The wider catalogue includes batteries and controls that form the surrounding system rather than being interchangeable parts of the inverter.

Products and platforms

  1. DataHub

    Plant controller

    RS485 controller supporting up to ten X3-ULTRA inverters in the documented arrangement.2

  2. Adapter Box G2

    Heat-pump interface

    RS485-connected accessory with dry-contact, SG Ready or analogue heat-pump outputs.2

Technology

SolaX's X3-ULTRA communications guide explains how its RS485 connector separates two buses and how DataHub, an EV charger and Adapter Box G2 connect. DataHub can coordinate up to ten X3-ULTRA inverters and connect the installation to SolaXCloud. The adapter can pass control to a heat pump through dry contacts, SG Ready or an analogue output. These are unusually useful integration details because they identify actual equipment roles and wiring boundaries. The connector's network-cable shape does not make it Ethernet, and the manufacturer explicitly warns that a fully populated cable is unsuitable for some accessory connections.

Markets

The X3-ULTRA product page positions the family across residential, commercial and industrial installations, while the company catalogue presents different inverter and storage ranges for different project sizes. Its household energy controls are particularly relevant where an owner wants excess generation to charge a vehicle or contribute to heating. SolaX's communications example shows that flexible-load control can involve a dedicated adapter rather than a direct heat-pump connection to every inverter. The official contact directory provides separate local offices and support contacts, helping buyers establish the market-specific product and installation route.

Company

SolaX's company history records its founding in 2012 and subsequent international expansion. The current corporate contact page gives its China office in Hangzhou, Zhejiang, alongside regional contacts for other markets. Its public company identity is SolaX Power Network Technology (Zhejiang) Co., Ltd., which is distinct from the local distributor or installer supplying a particular system. The business describes a portfolio spanning photovoltaic conversion and storage rather than a single inverter model. Its product support includes both conventional manuals and a technical knowledge base, where concrete connection examples document how the surrounding energy-control products are used.
