Risen Energy adds full liquid cooling to 131 kW/261 kWh C&I storage unit

<p class="p1"><span class="s1">Risen Energy says its new 131 kW/261 kWh commercial storage unit uses silicon carbide and full liquid cooling to improve efficiency, maintain output in hot conditions, and speed up installation.</span></p><p><strong>From <a href="https://www.ess-news.com/2026/02/13/risen-energy-adds-sic-and-full-liquid-cooling-to-new-131-kw-261-kwh-ci-storage-unit/" rel="noopener" target="_blank">ESS News</a></strong></p>
<p>Risen Energy has launched a 131 kW/261 kWh commercial-and-industrial (C&amp;I) battery energy storage “all-in-one” unit featuring a full liquid-cooling architecture and a silicon carbide (SiC) power conversion stage, positioning the product as a higher-efficiency upgrade for behind-the-meter applications.</p>
<p>According to information released by the company, the new unit raises PCS rated power from 125 kW to 131 kW to better support high-frequency operating strategies such as two charge/two discharge cycles commonly used in C&amp;I arbitrage and demand management.</p>
<p>A key change is the use of SiC MOSFETs in the PCS. Risen Energy claims the switching frequency is three times that of conventional IGBT solutions, cutting device losses by 40% and lifting PCS peak efficiency to 99.1%. It also reports a system round-trip efficiency of 90%.</p>
