Thanks Coulomb, I call a Electrician he checked everything but couldn't find solution, i showed him this video and some other videos from YouTube too. My case is strange even Electrician said first time he is experience this kind of problem. If earth is used as neutral or earth is connected to neutral, light should turn on in any load not between 200w-700w. Anyways if i find any solution i will share on this fourm. Thanks.

Thanks Scorp007 One more question, when pv is less just enough to carry load but not enough to carry load and charge battery simultaneously in that case what should be the priority SBU or SOL.

Hi, We have cloudy weather these days not enough PV to charge battery as well as load shedding so SBU mode will drain the battery. what combination you suggest SOL & CSO or SOL & SNU for cloudy weather. Current settings settings 1 SBU settings 12 12.5v settings 13 full settings 16 SNU settings 29 11.90v Thanks

Thanks Scorp007 & jumper for detailed explain.

Thanks Scorp007 my current float charging is 13.5v and bulk is 14.6 as per battery data sheet. There will be no harm if set float to 13.8v?

Hi, confusion about settings 13 settings 1 SBU Back to battery mode at 13.5v means battery is fully charged ? if not means battery always remain under charge? Thanks

Hi, Found the reason of fault 02, infact the warning indicator 02 and that is for low battery. Unfortunately my inverter is old model (delux power max 1200- 900w) and doesn't have user manual. I downloaded user manual for another brand which have similar functions. After changing the battery problem solved. Thanks Coulomb & Scorp007 for help.

Yes fan is running while discharging. And no error 04.

No load is always within the limit. Error disappear automatically when grid is on. Error appears when battery voltage 12.1v under load around 200w.

Hi, I made some experimental changes and now error code 02 appears. when grid off after 30 minutes inverter starts warning but doesn't shut off , continue running for next two hours then grids on. Load was around 200w. Now This happened every time grids off. Battery is fully charged on floting stage 13.3v I change back to old settings but problem still there. This is my settings. Battery 185Ah(Tall tubular deep cycle) system 12v panel 150x4 program 1 SBU program 2 30A program 5 USE program 12 12.30 program 13 FULL program 16 SNU program 26 14.30 program 27 13.30 program 29 11.90 Please help. Thanks

That's good but i am afraid if battery discharge till 12.2v may not fully charge again since i have small system and heavy load shedding. Any way i will give a try.

Thanks for you suggestion i will change charge current to 30A but i don't want to compromise on battery life.

Tall tubular deep cycle . Program 1 sbu

Hi, I need help for inverter settings. We have heavy load shedding around 6 to 8 hours. Bellow is my current settings. Battery 185Ah system 12v panel 150x4 program 2 20A program 5 use program 12 12.80 program 13 13.80 program 16 snu program 26 14.10 program 27 13.50 program 29 12.50 Thanks
