24kW + 30kWh! SUNDTA Wipes Out a Polish Family’s Electricity Worries!

Warsaw, Poland / Shenzhen, China – April 15, 2026 – SUNDTA, a fast-growing energy storage specialist, today announced the successful commissioning of a 24kW + 30kWh residential energy storage system for a customer in Poland. The project, built around two Deye 12kW hybrid inverters, now fully covers the family’s daily electricity needs, significantly reducing grid dependence and lowering energy bills.

The Polish homeowner selected SUNDTA after evaluating multiple options. The final system combines dual Deye 12kW inverters (total 24kW) with SUNDTA’s own high-voltage lithium battery bank of 30kWh usable capacity. The installation seamlessly integrates with existing rooftop PV, achieving stable power output and high round-trip efficiency.

Deep Partnerships with Tier-1 Inverter Brands

The success of this project highlights SUNDTA’s strong technical collaboration with world-leading inverter manufacturers. “We have built deep, long-term partnerships with top-tier brands including Deye and Solis,” said a SUNDTA spokesperson. “These relationships allow us to offer perfectly tuned solutions where our batteries communicate natively with their inverters, ensuring plug-and-play reliability and maximum system efficiency.”

Thanks to these partnerships, SUNDTA’s proprietary lithium batteries are pre-tested and certified to work with the vast majority of inverters on the market, including Deye, Solis, Growatt, GoodWe, and others. End users benefit from:

• Enhanced safety – multi-layer protection (BMS, fuses, temperature control)

• Proven reliability – rigorous factory testing and real-world validation

• Stable, high-efficiency power – low self-discharge and high charge/discharge efficiency across a wide temperature range

• One-Stop Solution for Any Home or Business

Beyond supplying high-quality batteries, SUNDTA offers a complete one-stop solar-storage solution. The company supports customers from initial design to final commissioning, covering:

• Custom system sizing and configuration

• Product selection (inverters, batteries, panels, accessories)

• Technical documentation and wiring diagrams

• After-sales support and remote troubleshooting

For customers who already have an existing design or partial equipment, SUNDTA provides technical and product configuration services to optimize their system – whether upgrading an old battery, adding storage to an existing PV array, or reconfiguring inverter settings for better performance.

“We Solve Real Family Needs”

“Our Polish customer needed a system that could handle both peak loads (heat pump, EV charger, kitchen appliances) and provide overnight backup. The 24kW inverter power plus 30kWh storage exactly matched their 7kW average load and 4‑hour autonomy requirement,” the spokesperson added. “After installation, the family now runs almost entirely on solar during the day and stored energy at night, cutting grid purchases by over 85% in summer months.”
