SolarMax

What SolarMax does

SolarMax is a brand of photovoltaic (PV) string inverters serving residential and small commercial solar installations. The portfolio spans single-phase units (SP series, 1.5–3 kW with 1 MPPT) for residential rooftop use and three-phase units (SMT series 6–13 kW with 2 MPPT achieving up to 98.2% efficiency; TP2 series 5 kW with Ethernet) for commercial applications. All inverters include built-in online monitoring, which feeds the brand's MAX portal ecosystem: MAX.STORAGE for storage systems, MAX.WEB for web-based inverter management, and MAX.LINK for linked-device performance tracking.

Revenue is generated through two streams: one-time hardware sales of inverters priced €199.99–€479.99 per unit, and recurring subscription fees for advanced monitoring (€5.95 monthly, €29.99 for six months, €59.50 annually). Distribution is concentrated through a single authorized online retailer, helivar.de, operated by JARVIS IT Projekt- und Handels GmbH, which serves 21 countries across Europe, North America, Asia Pacific, and the Middle East with localized pricing and payment options.

The company's customer base is fragmented across residential homeowners and small commercial buyers purchasing individual units via e-commerce. There are no disclosed enterprise or utility customers, no parent-company information, no funding history, and no management team data in the available record. The brand's competitive position rests on a value-tier price point, a coherent SP/SMT/TP2 product range covering 1.5–13 kW, and a unified monitoring portal suite.
