Lithium Batteries in OSN POWER
7.92KWH-50KWh Fully Integrated Energy Storage Energy Storage System for Home Storage
Apr , 21 2021

The OSN-ESS-48165 is a 15.84 kWh fully integrated energy storage and management solution with Voltronic Electric equipment. Energize and protect your home or business from power outages and lower your utility bills with this safe, simple, reliable and practical energy storage system. The OSN-ESS-48165 system includes all the equipment you need in one enclosure: (x2) 7.92kWh 48V LFP (Lithium Iron Phosphate) batteries, a built-in Voltronic inverter (5.5KW), it can be used on- or off-grid and integrates seamlessly with new or existing solar installations.

The OSN-ESS-48165 stores electricity from solar, wind, diesel/gas generators, the grid or any combination. Programmable for time-of-use, peak-shaving, self-consumption, and back-up power. The system features an internal transfer switch that automatically disconnects from the grid during power outages and provides standby power for critical circuits.

It shares key battery bank parameters with inverter improving overall system performance of 48V battery bank. Simple and safe, the system requires no maintenance, thermal monitoring, cooling, fire suppression, or ventilation equipment.

For additional energy storage, the OSN-ESS-48165 is scalable to meet any energy requirement by connecting additional enclosures. Environmentally friendly and will be Certified to UL, IEC and CSA standard.

From our study, now LG ESS is 9.8Kwh, Sonnen: 10KWh, Tesla: 13.2KWh, Simpliphi: 15.2KWh.

If we make each of our battery module 7.92KWh, we can stack 15.84KWH with 2 modules.

And we can sell our all-in-one 15.84KWH ESS less expensive than Simpliphi 15.2KWh batteries.

•Scalable Li-Ion battery expansion

•Module design, 7.92KWH per module, UP to 5.5KW output from inverter

•Smaller size, better for home storage use

•Each inverter can stack 13 max. battery modules, and max. 6 inverters can be paralleled. that is to say: 13*6=78 modules max.


· SIA (Standard Interconnection Agreement) customers: ESS allows for solar PV power to be self-consumed in a DC Coupled system, curtailing PV production to prevent the export of power to the grid

· NEM (Net Energy Metering) customers: add standby power to an existing net-metered solar array or peak-shaving to a new net-metered solar array

· Disaster recovery customers: reliable, 98% efficient, non-toxic backup power in the event of a power outage
