Use solar after sunset
Store daytime generation and use it in the evening or overnight.
Battery Storage That Replaces the Diesel Genset
Batteries store solar power so you can use it after sunset, ride through outages and run less diesel. WRS can supply storage as a project or as a service.
Who it's for
Is this right for you?
- You run diesel gensets for backup or for peak loads.
- You use power in the evening or at night, when solar is not generating.
- You pay demand charges that batteries can help cut.
- You need temporary power for an event or a site, without a genset.
Process
How battery storage works with solar
- 01
Solar charges the battery
Surplus solar power is stored instead of being exported at a low rate.
- 02
The battery supplies your load
After sunset, or during peaks and outages, the battery supplies your site.
- 03
The controller coordinates everything
Solar, battery, grid and any diesel set work together, so the genset runs only when needed.
What storage can do for you
What storage can do for you
Cut peaks and demand charges
Discharge during peak periods to lower the maximum demand you are billed for.
Backup that does not burn diesel
Keep critical loads running through short outages, with the genset as a last resort.
Storage as a service
For events, short projects or pilots, WRS can supply batteries as a service rather than you buying them.
What it costs and what you save
The right battery size depends on your load profile and what you want storage to do. We model the options and set out cost and savings in a written proposal after the free assessment.
