Gramo Starter Plus comes with 3 panels and a long-lasting lithium-ion battery (8–10 years), offering more backup time and higher performance.

In contrast, Gramo Mini has 2 panels and a tubular battery that lasts 2–4 years.
Gramo Mini Plus is ideal if you want more power and less maintenance.

This system supports essential appliances such as:

• 2-3 Led Bulb (5 to 10W each)

• 1 standing fan (50-70W)

• 1 Laptop (40-60W)

• WiFi router or decoder

• Phone charging (2-3 phones)
  All at once — as long as the total load stays within 150W for longer backup time

No. These appliances typically require high power or surge current.
This system is not suitable for:

• Fridges or freezers

• Electric irons

• Microwaves, kettles, or pumping machines

• Air conditioners

Yes, it can — but with important limitations.

The Gramo Starter Package can only power a 500W washing machine if it has no surge.

If you plan to use a washing machine regularly, especially alongside other appliances, we recommend upgrading to a higher solar package with larger battery bank or 24V system.

Yes, you can upgrade the panels or battery over time. Contact Gramosolar for expert guidance.

With a full battery (50% DOD), this system can power:

• 50W load for about 12 hours

• 100W load for about 6 hours

Your maximum load after sunset should not exceed 50W to enjoy longer backup time.

Daytime solar input (with 1600Wh from 4 peak sun hours) is enough to recharge the battery fully and power light to moderate loads during the day.

Yes, but only for light loads.
To run for 24 hours, your total usage should stay around 50W (e.g., lights, fan, WiFi router, phone charging).

For higher loads like 200W continuously, the system will only last about 4-5 hours, so an upgrade would be needed for full-day heavy usage.

To power your home or appliances continuously for 24 hours using this solar system, you’ll need to manage your energy consumption wisely..

👉 To make the system last for a full day:

• Reduce your total load to around 50W or less (e.g. LED bulbs, fan, WiFi router, laptop)

• Use heavy appliances (Between 200-300W) only during daylight hours when solar power is active

• Avoid running multiple high-wattage appliances at the same time

The number of appliances you can power at once depends on their combined wattage, not just the quantity.

The safe simultaneous load limit is about 50–100W if you want longer backup time and smooth performance.

✅ Appliances You Can Power Together (Example at 150W Total):

• 3 bulbs (30W)

• 1 × Standing fan (30W)

• 1 × Laptop (60W)

• 2 × Phone chargers (30W total)

Total = 150W → Well within this system’s safe operating range.

⚠️ Do not use this system to power  the following devices:

• Electric irons

• Microwaves or kettles

• ACs, Freezer and high wattage washing machines 

These appliances require high wattage or surge power which is beyond the capacity of the inverter.

🧠 Pro Tip:

Think in watts, not number of devices. Just add up the wattage of what you want to use. As long as the total stays under 350–400W, you’re good to go!
