Can you share insights into your latest advancements in battery energy storage systems and smart home energy management?
We’ve extended the architecture that built our leadership in the residential segment into a unified ecosystem tailored for C&I applications. Our air-cooled battery systems, hybrid inverters/PCS, and EMS all operate under a single SolaX Cloud platform for seamless monitoring and control. For the C&I air-cooled series, our systems are designed for long-term reliability, offering up to 6,000 cycles at 90% DoD under 0.5C operation conditions, with a guaranteed residual capacity per the product’s official warranty terms. The system integrates Tier-1 cells and SolaX-developed BMS, PCS, and EMS technologies, ensuring tightly coordinated performance. A high-efficiency air-cooling design maintains uniform temperature across modules through intelligent airflow management and multi-point temperature sensing, ensuring stable SOC/SOH estimation with AI-enhanced control logic.
On the smart-energy side, SolaX Cloud acts as the coordinating brain. Beyond real-time control, it performs data-driven optimization.
In some countries (such as Germany, the United Kingdom, Belgium, and Australia), there are requirements to limit the grid-connected power of PV systems. Any electricity exceeding the grid connection limit will be discarded.
Electricity prices generally exhibit fluctuations, with some countries experiencing significant variations. For example, the daily electricity prices in Finland can vary greatly, with the highest prices being over 6.8 times higher than the lowest prices, or even more.
XSchedule is a system that flexibly adjusts the inverter/battery operating mode and system energy treatment based on PV intensity, load forecasts, and intraday electricity price differences, aiming to maximize PV energy utilization and revenue.
By adjusting the battery’s charging and discharging times, excess power that would otherwise be wasted due to grid restrictions on power generation is utilized, thereby increasing power generation.
According to electricity price fluctuations, it adjusts the operating mode and controls the charging and discharging times of the battery to maximize economic return.
What are your main priorities and strategic goals for Romania and the Balkans region in the next years?
Our main priority in Romania and the Balkans is to extend the success SolaX has had in the residential PV + storage segment and scale that know-how into the C&I and utility markets.
We want to use the same proven control algorithms, energy management strategies and system architecture that worked so well in homes and apply them to larger projects with our new product range.
How would you describe SolaX Power’s current footprint in Romania and the potential you see here?
SolaX is present in Romania since 2018. Literally! The first inverter was installed back then and it is still operational right now. It has more than 47000 operating hours. Some years later the decision from SolaX headquarters in China was to create a local team in Romania, that is also responsible for the whole Balkan Area (Bulgaria, Serbia, North Macedonia etc.). We are now a team of 9 people and looking forward to growing much more in 2026. With this local team SolaX is offering constant support to all the partners who buy and install the products. Also, in terms of marketing and visibility SolaX is among the top brands in the renewable energy sector, having participated to conferences and expos all around Romania and the Balkan countries.
How do you assess Romania’s progress in the shift toward renewable energy and decentralized energy systems?
Romania has made impressive progress in renewable energy, especially in solar, with total PV capacity projected to reach 6–7 GW by the end of 2026. The prosumer sector has exploded, now exceeding 250,000 households and businesses with rooftop systems contributing to nearly half of the national solar output. Based on the strong government support such as the “Casa Verde Fotovoltaice” subsidy program net metering, and EU funding has accelerated adoption across all market segments. At the same time, rapid growth has exposed grid challenges like congestion, curtailment, and the need for storage and flexibility. These pressures are pushing investments in smarter infrastructure and battery systems. Overall, Romania is transitioning quickly toward a decentralized, resilient energy model, making it a promising and technically exciting market for advanced PV + storage solutions.
Are there any upcoming projects in Romania or the Balkans that you can reveal today?
The main market demand for 2026 is related to large, utility storage systems. SolaX comes with a premium product, called ORI: Original, Robust, Intelligent. Since the first months of its official launch in Europe, the company can boast of a project signed in the UK with an impressive total power: 2000 MWh. This will be implemented in the first half of 2026. On the Romanian market, we started promoting the ORI product in November and we expect the first contracts to be signed in Q1 2026.
Of course, SolaX will continue to focus on selling established products: inverters and batteries for the residential segment. The new heat pumps will also make their way there, which will be a game-changer. Also, in the C&i segment, demand is growing visibly, so we expect significant figures in 2026 with the AELIO and TRENE products.
How is SolaX preparing for increased demand for storage as more prosumers enter the market?
SolaX already has an impressive production capacity. The company owns one production plant in Tonglu, China.
For 2026, a new massive investment of 136 million euro has been made. it’s for Phase III Factory Project (Heatpump and Utility storage production line), with an Utility Storage Annual Capacity – 15GWh
It is also worth mentioning that SolaX has the possibility at any time to supplement production in any of the plants by up to 200% (3 times), thus quickly responding to market demand, if it increases dramatically.
What is SolaX’s long-term vision for supporting a carbon-neutral future in Europe?
At SolaX, our long-term vision for supporting a carbon-neutral Europe is to drive the transition toward a fully decentralized and intelligent energy ecosystem.
We’re building on our proven success in the residential sector to expand into commercial, industrial, and utility-scale applications with advanced energy storage solutions like the AELIO and TRENE series.
Our focus is on delivering fully integrated systems combining inverters, storage, EV chargers, and smart energy management that enable maximum self-consumption, grid interaction, and virtual power plant integrations. By investing in R&D, digital platforms, and strong local partnerships, we aim to empower prosumers, businesses, and communities to take an active role in the energy transition and help shape a cleaner, smarter, and more resilient energy landscape across Europe.
