Wanted Schneider Electric Charge controller

Regarding the additional solar charge controller for the elderly couple, the Schneider MPPT 60, MPPT 80, and MPPT 100 are all highly reliable and proven solutions.

To recommend the most suitable model, could you please confirm the following details?

• Total solar panel capacity (W)
• System voltage (12V, 24V, or 48V)
• Existing charge controller model (if any)
• Battery type (Lead-acid or Lithium)

As a general guideline:

• MPPT 60 – Up to 60A charging current, suitable for 12V/24V/48V systems, supporting approximately 800W (12V) to 3,200W (48V) of solar power.
• MPPT 80 – Up to 80A charging current, ideal for larger residential systems with higher energy demand.
• MPPT 100 – Up to 100A charging current, recommended for large residential or commercial solar installations.

Recommendation for the elderly couple:

If their system mainly powers basic household loads such as lighting, a refrigerator, TV, or small appliances, the MPPT 60 is usually sufficient and offers the best value for money.

If they regularly operate larger loads such as air conditioners, water pumps, or other high-power equipment, the MPPT 80 or MPPT 100 would be a better choice.

All three models are user-friendly. Once the parameters are configured by the installer, the system can operate automatically with minimal ongoing maintenance.
