The "Best Partner" of Roof Photovoltaic: Energy Gathering New Energy Home Energy Storage Makes "Spontaneous Self-Use" a Reality
time：2026-09-01
The morning sun shines on the photovoltaic panels on the roof, and the current quietly flows into the household energy storage battery; In the evening, the family sits around the living room, and the TV, air conditioner and lighting are all switched from the mains to the energy storage power supply; late-night power grid trough, battery charging silently, reserve energy for the next day. The life picture of "light and storage linkage" in this scene is changing from concept to daily life of more and more families. In this picture, a reliable household energy storage battery is the core hub connecting photovoltaic power generation and household electricity. The family energy storage product line, which gathers new energy sources, is changing "spontaneous self-use" from the slogan of environmental protection to economic reality in multiple forms such as wall-mounted and stacked.
DGPI-SE-001 wall-mounted energy storage: "Energy manager" on the wall ". The slender size of W500mm × D249.5mm × H800mm is equivalent to the height of the kitchen console, which is naturally integrated into the home environment visually. The weight of 132kg is fixed with the bearing wall by expansion bolts, and the safety factor of static load exceeds 3 times. 5.12kWh of large-capacity energy storage, combined with intelligent BMS peak-Valley scheduling strategy, during the day when the photovoltaic surplus is charged, the evening electricity price peak discharge, the photovoltaic spontaneous self-utilization rate increased from 30% to more than 80%. Based on the peak-valley price difference of 0.6 yuan/kWh, the annual electricity bill is saved by more than 3,000 yuan, and the payback period of investment is about 5-7 years.
Safety gene of lithium iron phosphate. Home energy storage is installed in the living space, and the safety is the uncompromising bottom line. The energy gathering new energy adopts large monomer square lithium iron phosphate batteries, and the temperature of thermal runaway is as high as over 500 ℃, which is stable in abuse scenarios such as acupuncture, extrusion, overcharging, etc. Compared with ternary materials, lithium iron phosphate shows slow heating rather than violent combustion when the heat is out of control, and does not release combustible gas, thus gaining precious time for the evacuation of family members. The cycle life of more than 6,000 times, the theoretical life of more than 15 years in the daily uniform charging scenario, and photovoltaic systemMatch the design cycle.
Energy economics of smart BMS. Self-developed BMS, which gathers new energy, is not only a protection circuit, but also a "digital brain" of household energy ". It is deeply linked with photovoltaic inverter and home energy management system (HEMS), and intelligently optimizes charging and discharging strategies according to photovoltaic output, load curve, grid electricity price and weather forecast. When the load peak is summer air-conditioning, the first discharge will reduce the cost of purchasing electricity; In winter heating season, the heat pump will cooperate with the heat pump to realize the coordination of "light and heat storage"; When the power grid is cut off, it will switch to off-grid mode in milliseconds to ensure the refrigerator, critical loads such as network and lighting are uninterrupted.
Market evolution from "matching" to "just need. With the surge of distributed photovoltaic installed capacity and the expansion of price difference between peak and valley electricity, household energy storage has evolved from "photovoltaic matching" to "independent just need". The wall-mounted design of energy-gathering new energy enables the energy storage system to get rid of the shackles between devices and enter the living room, entrance and balcony to become household appliances. After a European family adopted the plan, the annual electricity purchase decreased by 75%, the carbon footprint decreased by 4 tons, and the energy autonomy increased from 20% to 85%.
When energy is transformed from industry to family, wall-mounted energy is used for new energy sources. Energy storage and intelligent management, make every roof become a micro power station, and make every family become an energy producer and consumer. After all, for ordinary families, the best energy storage is not the strongest, but the most "imperceptible"-because it makes green life change from slogan to habit.
