SolarEdge battery loses charge overnight while idle
Your SolarEdge battery loses far more charge overnight while sitting idle than its standby draw explains, such as dropping from 50% to 40%. This page covers what to check first and the cause behind it.
What to check first
- Note the battery's percentage when it goes idle in the evening and again in the morning, and the hours in between.
- Look at the night-time draw in the app. A constant 20 watts would only account for about a 2% loss overnight.
- Overnight losses of about 1 to 3% are reported as normal. If yours is far higher, ask your installer to take it to SolarEdge technical support.
