Gramo Mini 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:

• 1 TV (up to 100W)

• 1 standing fan

• 3–5 LED bulbs

• WiFi router or decoder

• Laptop

• Phone charging
  All at once — as long as the total load stays within 300–400W.

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 Mini Plus has enough capacity to run a 500W washing machine, but you’ll need to use it wisely to avoid draining the battery too quickly or overloading the system.

✅ You can safely use it if:

• The washing machine is the only appliance running, or you add only light loads like a bulb or router.

• You’re using it during the daytime, while solar is active.

• Your machine is an energy-efficient model (preferably without an inbuilt heater).

• The washing cycle is short (30–45 minutes).

🚫 Avoid using it if:

• You want to run multiple appliances at the same time (like a fan, TV, or blender).

• The machine has a heating element, which can spike power demand beyond 1,000W.

• You rely on it for frequent or extended use at night when you’re running on battery alone.

Even though the 2.5kVA inverter can technically handle up to 2,000W (with safety margin), high-wattage appliances drain the battery fast. Gramo Mini Plus is better suited for moderate daily use — not heavy-duty, repetitive washing loads.

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

With a full battery (80% DOD), this system can power:

• 100W load for about 20hours

• 200W load for about 10 hours

• 300W load for about 6-7 hours

Daytime solar input (with 4,800Wh 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 100W (e.g., lights, fan, WiFi router, phone charging).

For higher loads like 300W continuously, the system will only last about 9–10 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 100W or less (e.g. LED bulbs, fan, WiFi router, laptop)

• Use heavier appliances 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 300–400W if you want longer backup time and smooth performance.

✅ Appliances You Can Power Together (Example at 350W Total):

• 1 × LED TV (100W)

• 1 × Standing fan (60W)

• 3 × LED bulbs (10W each = 30W)

• 1 × WiFi router or decoder (20W)

• 1 × Laptop (60W)

• 2 × Phone chargers (40W total)

Total = 310W → 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 and may overload the inverter or drain the battery quickly.

🧠 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!
