Not all solar systems are built to work together.
We’re seeing more and more homes with large battery systems but solar arrays that simply aren’t big enough to keep them charged.
💡 Here’s a real example:
⚡ 42kWh Battery
☀️ 4kW Solar System
That battery can never perform the way it was intended because there just isn’t enough solar production feeding it.
Even a 6.6kW solar system can take 2–3 days of good sunshine to fully recharge a 42kWh battery from empty.
A battery is only as good as the solar system charging it.
At WIEDERS Elect & Solar, we don’t believe in overselling equipment. We design solar systems that actually suit your home, your energy usage and your battery.
