Axinar has launched SolBox, a direct PV water heating system that powers electrical resistance accumulators without thermal collectors. Designed for homes and businesses, it offers real-time monitoring, MPPT optimization and automatic grid backup.
Greek heating specialist Axinar SA has introduced SolBox, a direct photovoltaic system designed to produce domestic hot water all year round without the need for thermal collectors.
The system uses electricity generated by PV panels to directly power the electrical resistance of a water accumulator. It is entirely designed and manufactured by Axinar, utilizing the company’s in-house technical capabilities in both photovoltaic and thermal technologies.
SolBox is offered in four versions: Light (2 panels), Family (3 panels), Pro (6 panels) and Custom (1–6 panels). Standard configurations include 100 to 500 liter electric resistance batteries.
The solution is available from the manufacturer’s website, with the Light version costing €1,240 ($1,439), the Family version costing €1,488 and the Pro version costing €2,232. Customers can also purchase the SolBox device alone, with access to the accompanying mobile app, for €806.
According to Axinar, when using the system, no administrative procedures are required to supply electricity back to the grid.
From a technical perspective, SolBox uses a maximum power point tracking (MPPT) perturbation and observation algorithm to optimize solar energy use in real time. By operating without an inverter, the system reportedly achieves more than 30% higher energy consumption all year round with a limited number of panels. It can also capture energy at low irradiance, at sunrise or sunset, and during partial cloud cover.
The equipment comes with integrated overvoltage and lightning protection. A dedicated app is also available for technical support and remote monitoring of electrical parameters.
Users can manage SolBox through a mobile application, which provides instant production monitoring, comparison of historical data and temperature programming on daily, weekly or annual schedules. The electricity grid serves as an automatic backup if necessary.
Axinar positions SolBox for a wide range of applications including private residences, tourist accommodation, restaurants, hair salons, light industrial facilities, car wash stations, prefabricated housing, remote locations and institutional use.
