Hello to all, I am new to this interesting thread, I have read it from beguining more than one year ago, to the end some days ago. As you can see, English is not my language, I learned a bit in school about 50 years ago. I live in Guatemala, (Central America).
I have installed a solar system in my holiday place, where there is no electricity and is located in the jungle to 7 hours from the city where I live.
The system consist of 2Kw solar panels, two 40A MPPT controllers, 15840Wh @ 24 Volts Gel batteries , and the PJ inverter. My loads are only a fridge, 3 electric fans, some light bulbs... and a electric shower pulling about 1900W for short periods of 5 minutes or less, three or four times a day.
I have 3 PJ inverters, two 6000w and one 8000w, 24VDC/110VAC. I only use one at a time and have the others as backup. This inverters can carry the loads without any problem. The three inverters are fitted with the miracoluos Oztules E ferrite core with 9 turns of flat 20 square mm. enameled wire, and the idle current is only 0,4 to 0,5 amps ( wondeful).
Temperature here is 24C to 32C all year arround but the real feel is much more due to the high air humidity can easily reach 95% in some parts of the year.
As it is a very distant place, I can only go one 5 or 6 times a year, so when I get back to town, left turned off the inverter. the problem is that when I come again, sometimes the inverter does not want to start... and it is time to put to work the backup inverter, then I pull the inverter and let in the sun two or three hours to make it get warm and after that the inverter comes to life again, this has happened more than 4 times in last year. But the last time the inverter was burned in the middle of the night with only two LED bulbs lit, 10 wats each.
Anyone has an idea of what to do?.
I have sprayed the control and main boards with WD40 (water displacement fluid similar to CRC) but it seems no to be helpful
Any help will be very grateful
