Load shedding & batteries · Faisalabad, Lahore, Punjab

Do I still need a generator if I have solar?

Short answer

For most homes with a hybrid system and battery, no. The battery covers normal load shedding. A generator still makes sense for long outages, fog weeks with little sun, heavy loads such as factories, or sites where power must never stop.

If you keep one, it must connect through the inverter’s generator input where the model supports it, or through a proper changeover, never straight into the solar wiring.

Open Troubleshooting

When a generator still earns its place

  • Outages longer than the battery can cover.
  • Winter fog weeks when solar cannot recharge the battery.
  • Factories, hospitals or tubewells with heavy loads.
  • Sites with no reliable grid at all.

Battery

Covers normal load shedding.

Generator input or changeover

For long outages, fog weeks and heavy loads.

Never

A generator wired into the inverter output or back-feeding the grid.

Generator inputs are available on some Solis, GoodWe, Growatt and Huawei hybrid models, not all. Connection is technician work.

Connecting it safely

Some hybrid inverters have a dedicated generator input; others need a changeover switch. The connection is designed and installed by a technician, and a generator must never back-feed the grid or the inverter’s output.
