Gramo Starter Plus offer more backup time and long lasting battery than Gramo Starter. However, Gramo Starter is more affordable.
This system supports essential appliances such as:
3-5 led bulb (up to 50W)
1 standing fan (15 to 40W)
- Laptop (40-70W)
- Router (10-30W)
- Speaker (15-30W)
Mobile Phone (2 to 3 Units)
Power Bank (Up to 20,000mAh)
All at once — as long as the total load stays within 200–250W.
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
It can power washing machine under 800W with no surge power. Best used for washing machine between 300 to 400W
✅ 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 1.8kVA inverter can technically handle up to 1,000W (with safety margin), high-wattage appliances drain the battery fast. Gramo Starter 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) and daylight sun hour, this system can power:
50W load for about 24 hours
100W load for about 10 to 15 hours
300W load for about 7 to 10 hours
Daytime solar input (with 2,800Wh 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 nighttime maximum load should stay around 80W (e.g., lights, fan, WiFi router, phone charging).
For higher loads like 200W continuously, the system will only last about 4–7 hours, so an upgrade would be needed for full-day heavy usage.
To power your home or appliances continuously for 24 hours with Gramo Starter Plus, you’ll need to manage your energy consumption wisely..
👉 To make the system last for a full day:
Reduce your total nighttime load to around 80W or less (e.g. LED bulbs, fan, WiFi router, laptop)
Use heavier appliances (300-500W) 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 80 –200W if you want longer backup time and smooth performance.
✅ Appliances You Can Power Together (Example at 350W Total):
Led Bulb (5 units, 50W)
1 × Standing fan (60W)
- 1 × Laptop (75W)
3 × Phone chargers (50W total)
- Power Bank (Up to 20,00mAH)
Total = 250W → 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 300–400W, you’re good to go!
