MENOMONEE FALLS, Wis., Nov. 10, 2026 (GLOBE NEWSWIRE) — Holu Hou Energy LLC (“HHE”), the premier provider of solar plus energy storage systems and the breakthrough “EnergyCluster” architecture and control platform for Multi-Dwelling Unit residential properties, has introduced the HoluPower 3.0 solar energy storage system. Its “modular stack” design delivers the solar industry’s lowest incremental cost of energy storage, with capacity configurable from 0kWh to 56kWh per MDU resident.
When integrated to the HHE proprietary EnergyCluster, the HoluPower 3.0 significantly reduces the cost and improves the economics for installing solar + storage on MDU properties. To date, the MDU housing segment is nearly absent of any PV generation for individually metered residences. Structural impediments—load variability, small load units and tenant churn for rental properties—have made installing and financing PV systems nearly impossible in this segment. HHE has eliminated these barriers with its EnergyCluster, which currently operates across more than 1,500 housing units, making it the most cost effective, efficient and productive solution for the MDU market.
If a home in the EnergyCluster has more PV generation than it needs for its own use, excess becomes available to any other residential unit in the cluster instead of the PV being curtailed or exported for little or no compensation. This means the generated energy value stays at avoided retail electricity rate for the asset owner. And fewer kilowatt hours of battery are required per residence in the cluster. Vacancy rates, vacation absence, time of day pattern changes, and tenant load pattern variability impact is all mitigated. The EnergyCluster can export on command if enrolled into a VPP and provide resilience to homeowners when the utility power is out. This delivers value for the installation beyond any possible alternative.
The MDU segment for USA total housing is about 50 million residential units, which makes solar on MDU’s one of the most underdeveloped energy markets in the country. More than half of the market is represented by states and localities that have combinations of high base utility electricity rates, high summer peak rates, demand charges, time of use rates, high exposure to grid outages, and virtual power plant (VPP) opportunities. As such, the MDU served available market segment is likely worth greater than $250 Billion for the USA alone.
EnergyCluster is the only proven solar + storage platform for the MDU market, having been in commercial operation and proven bankable for greater than 5-years. The HoluPower 3.0 is currently in commercial operation across multiple EnergyClusters. The product has been designed to maximize homeowner and utility data security and is FCC compliant. It provides the utmost safety performance and meets all major USA certifications.
HHE will install over 3,000 HoluPower 3.0 systems in its own company developed and Solar ITC safe harbored MDU’s over the next 3-Years.
