Bro there are many chinese brands available. And also chinese copies of some famous brands. Market is flooded. I m using 5kv solar system wth orignal german made solar cells which are expensive thn chinese panels.almost double the cost of chinese. If u are buying chinese kindly chk the volts amps and compare it wth the panel specification. Normally it differs from 15- 30%.

Can you post pics of your system and panels please?

Hi all
i Have a infinisolar 10kw 3phase i can't run 1.5 ton a/c with it but with 3kw plus i can run the same a/C any one know why?

Hi.. I got 1 kva tesla solar inverter.. it's made by Voltronic
Before I install this..can I install it as DIY project...panels 300 watts already installed and cables plus controller connection done to battery and homage UPS

Question..
I have only Live red wire AC output from ups and no neutral wire as it it s shared by general elect fitting but this hybrid inverter has two wire for AC output along with ground wire...expert advice required as if I need to add neutral wire to whole house circuit it will be difficult

U need to hv two wire system. One neutral and other live wire (positive wire). Els it will nt work.

send me your mail i will draw you a diagram you will just need a 220 relay

[knmh84]

this is how i did it
all you need is a relay which you can buy in any electric equipment shop easily used for direct supply cutoff from wapda and generator
just cut you home supply wires
pass it using relay with normal open connection and touch wire A with A and B with B and you are good to go
but there is a small glitch with it
when wapda comes online the power from UPS Line which you used will be cutoff for a second and will come back online
but the faster switching relay can solve that problem if you can find one... i did not so i have that 1 sec gap for switching from inverter to wapda

for more you can call me on 0332-9409904
will be glad to help you out

You have a multimeter to check amps and volts of solar panel

Is that enough to check it or any physical thing can be checked too? i already know this procedure of multimeter

what i want to ask is that is there any other method? by the color of plates or the build quality etc
what i fear is that solar panel will show lets say 12V and after some months the voltages drop to 10 or 9V

Which city actually i bought Jinko solar panels of 2000 watt and satisfied with it.
No panles drop its efficiency as early as u said if you checked at shop and if panel not broken then nothing to worry.

You should consider panels of big companies as stay away from pathani maal

You shoud use a relay to cut off wapda when no wapda avalible so your system should be safe or if some electrition or you yourself make a mistake and change live to neutral and neutral to live
