do you have 2kv inverters,if there is what is the cost.
What’s the cost of 1000va
Dear sir/madam
We are running a solar installation office at the local, is that possible to supply the invertes to our area, kasaragod kerala if yes please quote for a demo inverter system
3kv price
It is a very interesting product 1kv Inverter with lithium iron phosphate battery supports 1000 W.To run a inverter A/C and fridge what is your suggestion for a inverter with solar energy.
will 2kv inverter support A/c or we need 3kv to support solar and suggest solar panel too
Hi Team,
I need inverter and also looking for distribution opportunity. Both the numbers given above switched off continuously. Can you give some alternate number.
Thanks
I need 1000v Invertor for my residence at Bangalore. Time being require one number. If the quality and performance satisfied require more.
Please share the details
1) can I connect solar panels charge controller with the LI-1250 sw inverter?
2) what is the price os 1.25 kw mppt inverter and one kw LIFePO4 batteries?
