How to Set Up Overnight Battery Charging on the SolisCloud App

Most Solar PV Systems installed by First Class Solar in Northern Ireland include solar batteries. With battery costs decreasing by a huge 90% over the last ten years, installing solar batteries has become an extremely cost-effective way for NI homeowners to save money on electricity bills

As a homeowner in Northern Ireland with a First Class Solar and battery system, the next step to save money is switching over to an Economy 7 Tariff of your choosing by contacting your current supplier. The final step to take full advantage of the battery benefits is overnight charging on your cheaper rate, and we’re here to guide you through self-setup for this on the SolisCloud app, step by step. 

Using SolisCloud to set up overnight charging on the cheaper tariff in Northern Ireland gives homeowners real-life, measurable benefits such as:

  • Lower electricity bills overall
  • Greater savings in low-sun periods
  • More predictable and full battery charge
  • Smarter energy management
  • Convenience and control in one app

Once you have navigated to the “Charge and Discharge” section, you can now set your charging time. 

Click on Charge Time Slot 1 and set this to run from 1am – 8am (or 2am-9am, depending on your cheap tariff times). Then click “Done” to save these times. 

Change the “Discharge Time Slot 1” to 00:00-00:00 to avoid having the solar batteries discharging to the grid. 

Change the “Time of Use Charge Current Set” to 50A and click “Save”.

Now your batteries are set to charge on the overnight rate, so you’ll wake up each morning to full batteries from half-price electricity.  

First Class Solar has seen firsthand the difference that overnight charging makes for residential homes in Northern Ireland – particularly over the winter months where solar production is lower. Being able to set the hours of charge allows you, the homeowner, the autonomy to choose when and for how long battery charging is required and to save money whilst you do so – you’re completely in charge.

Setting up overnight battery charging in the SolisCloud app is one of the easiest ways for homeowners in Northern Ireland to maximise savings for their solar battery system.
