Why Monitoring Your Home Battery Matters
A home battery isn’t something you should completely ignore after installation. A small amount of attention can make a big difference.
Lower Your Energy Bills
Check when your battery charges and discharges so you’re always using the cheapest energy available.
ESME can help here too, visit our price checker to find the best prices and tariffs, we can help you switch too.
Use More of Your Solar Power
Instead of exporting energy back to the grid, you can use more of what you generate.
Extend Battery Lifespan
Keeping your battery within healthy charge levels helps it last longer- saving you money over time.
ESME charges from 5% to 100% and then back to 5%. This is the most efficient use and protects the battery.
Reduce Grid Dependence
The better you understand your system, the less you rely on expensive peak-time electricity.
The 4 Things You Actually Need to Check
Most apps show lots of data - but you only need to focus on these:
1. Battery Level
Aim for 20%–80% most of the time
Avoid regularly draining to 0%
Use stored energy in the evening
2. Battery Health
A slow decline is normal
Sudden drops may need attention
Check monthly, not daily
3. Energy In & Out
Shows how fast your battery charges and discharges
Helps you spot when you’re using grid power unnecessarily
4. Your Usage Patterns
This is where real savings happen.
Ask yourself:
When is my battery full?
When do I use the most energy?
Can I shift usage to cheaper times?
A Simple Way to Save More
If your battery is full by mid-afternoon:
Run your dishwasher earlier
Do laundry during the day
Charge devices before evening
These small changes can reduce grid usage by up to 60–70%.
Tools That Make It Easy
You don’t need to be technical to monitor your system.
Mobile Apps
Most home batteries come with an app showing:
Battery level
Energy usage

Charging when electricity is cheapest
