✅ At Full Continuous Output (3,600 W):
You can run high-demand appliances simultaneously:
• 1.5 HP AC (~1,100–1,300 W)
• Refrigerator (inverter) (~150 W)
• LED Lighting (~50–100 W)
• TV + Wi‑Fi + decoder (~150 W)
• Laptop & Phone chargers (~100 W)
• Fans or other small appliances
Total load ~1,600–2,000 W. This unit handles it with room to spare and can cover even the startup surge of AC compressor.
🔋 Battery Runtime Estimate:
With 8 kWh usable:
• Light load (~1 kW) → ~8 hours
• Moderate load (~1.5 kW) → ~5–6 hours
• Heavy load (~2 kW) → ~4 hours
So expect 4–8 hours of backup, depending on usage.
⸻
♻️ Dual Charging Modes
• Solar charging: up to 1,000 W input
• PHCN/Grid charging: up to 3,000 W
Allows fast replenishment during the day from both sources .
⸻
✔️ Ideal For
• Whole-home backup during outages
• AC-heavy usage, thanks to robust inverter
• Rapid charging via solar and grid
• Portable or modular setups—the system comes on wheels (approx. 150 kg)
⸻
⚠️ Considerations
• Battery storage: 8 kWh is substantial but not unlimited—heavy 2 kW loads will drain in ~4 hrs
• No built-in solar panels—you’ll need to add up to 1 kW of panels separately
• Weight & mobility: at ~150 kg you’ll need a stable platform and possibly wheels for movement.

Mary –
Very portable solar system, the delivery was fast, been enjoying it I must say, the battery last long. I also bought panels to work during the day, it charges very fast.
Afolabi –
How many panel is needed for this system to run well
itelsolar –
This needs a minimum of 4 – 6 panels of 550w, with this the system will recharge in 3:40min – 2:30min. The maximum panel should be 9 of 550w
Paul –
How many warranty does this product have
itelsolar –
It has 2 years Replacement warranty and a 5 years repair warranty.
Eyituoyo Nathan –
I have been praying for a brand like itel to make something like this. I personally wrote to Zinox (iTec maker) to make something for me and my clients but they refused. I had to go for Ecoflow which is a more expensive brand. Thank you itel for this innovative product. Hope to purchase the unit soon
brownelvis923 –
I have this set up for my business. I have 12 panels of 400w. But, once I put load on it, it stops charging. I am using it for my frozen food business. 2 deep freezers and 3 fridges. What could be the reason. It works normally. But once I put load, the solar panels do not charge the system again
itelsolar –
This means the power generated by the panel is not enough to charge the battery and also power the load at the same time, quick fix allow the battery to fully charge than the power from the panel become free energy to use or increase the panel to generate more power
Benjamin –
Just a simple question
With this unit can I add an extra battery pack say 2.5kwh or 5kwh
The inverter is enough but on the stretch the battery would be insufficient.
itelsolar –
no you can not.
Terwase Anyiman –
do you deliver to Makurdi, and what is the process like
itelsolar –
We deliver nationwide
simply place your order and send payment proof
Adebola Sanni –
Can Additional batteries be connected to this to increase backup time?
itelsolar –
No it can not be added
Thank
itelsolar –
No it can not
Paschal .E. Okoye –
Itel please can you make 1kw inverter/ 2KVA battery solar generator
itelsolar –
Before the end of the year.
Thank
itelsolar –
expect it before this year end
itelsolar –
Yes
