Samduo launches residential AC-coupled plug-in storage systems

<p class="p1"><span class="s1">The Chinese manufacturer said its new Nex E6000 and Nex E6000H storage systems combine a 6 kWh battery, an inverter, and an integrated energy management system, with scalable design allowing multiple units to be networked for higher capacity and coordinated energy sharing.</span></p><p>Chinese energy storage provider Samduo, a unit of Shenzhen-based manufacturer Hubei Yixing Intelligent Equipment, has launched two new battery lines for residential applications at the Solar Solutions International trade show in the Netherlands.</p>
<p>The company said the Nex E6000 and Nex E6000H series will be available for sale in Europe starting in May.</p>
<p>“The Netherlands is preparing to phase out net metering by 2027, prompting around 500,000 households to upgrade to digital meters,” the company said in a statement. “Meanwhile, growing incentives, including VAT exemptions in Germany, are expected to further accelerate demand for AC‑coupled, plug-in solar storage solutions.”</p>
<p>Both models are AC‑coupled, requiring no direct DC connection to PV arrays, and support plug‑and‑play installation, which Samduo describes as a key advantage for retrofits and balcony-oriented living spaces.</p>
<p>The Nex E6000 integrates a 6 kWh lithium-ion battery, battery management system (BMS), and inverter into an ultra‑slim unit just 11.9 cm deep. It reportedly supports up to 8,000 life cycles and delivers 2,600 W bidirectional rapid charging, enabling efficient energy storage and discharge for daily use and peak‑shaving applications, according to the manufacturer.</p>
<p>The Nex E6000H expands household energy management capabilities with an ultra-fast one-minute setup and a smart energy management system, which facilitates networked energy sharing and coordination across up to 15 devices, totalling 90 kWh, via a single hub.</p>
<p>Both systems are IP65-rated and support Open API integration with popular European smart-home and energy platforms such as Shelly, HomeWizard, and EverHome, Samduo added.</p>
<p>The company claims the systems can deliver estimated annual savings of €562.30 ($648.50) based on a 4 kW residential PV array paired with a 6.03 kWh battery, assuming typical mid-latitude European solar conditions.</p>
<p>Under these assumptions, a 4 kW PV system would generate roughly 16 kWh per day, or 5,840 kWh annually. With a usable battery capacity of 5.43 kWh and assuming 90% depth of discharge, the storage system could supply about 1,980 kWh of energy per year. In this scenario, the base PV self-consumption rate without storage is 35%, rising to 75% with the battery installed.</p>
