A modular hybrid energy-storage solution for projects that need PV generation, grid interaction and LiFePO4 battery storage in one coordinated system.
The Integrated Grid Inverter and Energy Storage Unit series covers 7.2 kW, 12 kW and 15 kW options for single-phase and three-phase applications. Each configuration combines inverter control, battery management and a weather-protected enclosure for practical residential and light-commercial energy planning.

An integrated grid inverter and energy storage unit helps simplify the hardware architecture for a hybrid solar project. Instead of treating the inverter and battery as unrelated equipment, the system is selected around a combined operating window: PV voltage, AC phase, battery energy, current capability, installation space and backup priorities.
The supplied ESS HX and ESS LV series use a 51.2 V battery platform. The 7.2 kW and 12 kW ESS HX configurations are designed for 220/230 VAC single-phase requirements, while ESS LV 12 kW and 15 kW options provide 380/400 VAC three-phase output. This makes it easier to begin a technical discussion with a realistic configuration rather than an isolated battery capacity number.
For grid-connected installations, the site design still needs to follow local electrical codes, utility requirements and the final approved inverter settings. Share the intended destination, load profile, PV plan and backup expectation so YINEN POWER can help review a suitable configuration.

Values above are from the supplied product selection manual. Final model selection should be confirmed for the actual installation, grid code and balance-of-system design.
Store available solar energy for later household or commercial use when the site load and utility policy make on-site consumption valuable.
Define essential-load priorities, backup time and available battery energy before selecting a system configuration.
Evaluate ESS LV three-phase options for sites with 380/400 VAC supply and a matched PV and load profile.
Start with the site’s phase type, peak load, PV array plan, required backup loads and target backup duration. Then confirm the candidate ESS HX or ESS LV configuration with the final electrical design.
They are designed around grid-connected inverter operation, but final use depends on local grid code, certified configuration, protection design and utility approval in the destination market.
Send the destination country, requested phase type, PV module plan, intended loads, expected backup period, installation location and quantity.
IP65 is the published enclosure rating. The final location should still follow the manual, wiring rules, ventilation clearance and local installation requirements.
The available published capacities vary by system platform. Confirm the exact expansion plan and permitted configuration with YINEN POWER before procurement.
Share your inverter phase, PV plan, load profile, energy target, installation location and destination country for a practical configuration review.
