When it comes to commercial energy storage we are able to provide a variety of options. Depending on your situation and application we’ll be able to find the right solar and set up for you. Battery systems are pretty simple but here’s an outline of the four different types of storage set ups. 

Grid-tie is a common installation configuration for a photovoltaic (PV) or solar system. Grid-tie is also known as on-grid, grid tied, utility interactive, grid inertia, or grid-direct. In this application, electricity is generated by the photovoltaic (PV) solar system and routed to loads (component that consumes power i.e. lab climate control and lights), offsetting the utility electrical load of your operation. In many locations excess energy can be sold back to the utility providing your business with a form of revenue. 

Backup power systems incorporate energy storage of  our batteries. Batteries are charged through the utility connection and your PV solar system. When there are utility power fluctuations (brown-outs or outages), your systems inverter provides continuous power to critical loads. Battery power can also provide energy to assist when powering intermittent heavy loads, thereby reducing operating costs. 

Self-Consumption means that the energy generated by your PV solar system is consumed by your grow or business. When the price to buy electricity is higher than the price to sell it, the revenue due to self-consumption is higher than the profit of selling electricity to the grid. The objective is to consume 100% of the energy produced by the PV system, offset your peak power with your electricity you store your battery bank. 

Off-grid systems are completely disconnected from the utility grid. This system typically suited for grow’s that are too far from the closest utility transformer. In this configuration, energy is collected and stored to meet all power requirements. The addition of a generator provides additional autonomy, capacity for heavy loads, and battery charging when solar energy is reduced. In a scenario where a generator is providing prime power in an off-grid location, the addition of a PV system can offset the costs of both fuel and generator maintenance. We are proponents to working in greenhouse environments that utilize cogeneration or combined heat and power (CHP) is the use of a heat engine or power station to generate electricity and useful heat at the same time.


UL 9540 Certified Energy Storage System 

The right solution for commercial and industrial applications in conjunction with photovoltaic (PV) solar systems. Typical solutions are peak shaving, load shifting and photovoltaic self-consumption with or without associated Energy Management System (EMS).

Flexibility for Expansion

SUNSYS XTEND ESS enables modular flexibility if you want to expand your battery storage bank in the future. It’s a simple as connecting two lego blocks together by adding additional SUNSYS PCS² batteries from Socomec. Because the architecture of the equipment is certified UL 9540, no further certifications will be needed in case of future system expansion.The solution enables peak shaving, load shifting and photovoltaic self-consumption with or without associated Energy Management System (EMS).

Compact design

SUNSYS XTEND ESS is designed compact installation, either indoors, or in a weather-tight outdoor enclosure. The complete system includes:
• SUNSYS PCS2 bidirectional power converters
• Batteries
• AC distribution cabinet
• String Battery Coupling Panel (SBCP)

SUNSYS PCS² UL Lithium Ion Battery 

Reduce peak consumption and maximize PV energy self-consumption

SUNSYS PCS² can limit the impact of increases in the electricity retail price by:
• supplying the load to cut peak demand: peak shaving,
• maximizing the PV energy self consumption (use what you produce)
Any PV energy surplus is stored in the SUNSYS PCS² battery system. This stored energy is used later to supply the load.
