Hello all, please educate us !
We RV/ live in Mexico . Our solar (exactly batteries, quit long time ago)
and we were without own electricity for long time .
After long time of saving , we bought very
expensive , two, 24 v each, gel batteries, and two more panels .
We have right now 4 panels, 75W each and above two batteries .
The name of batteries brand is Cecasa, and they are from Spain .
We also bought new controller (Steca), which does all possible
readings .
For few days everything was great .
Now already we have problems . ( three weeks)
Problem number one is with computer .
If I use computer without access to electricity, and battery goes lower, let say to 70%, later connected in RV does not charge,
and connection of computer to electricity jumps literally every second on/off .
When I start to use computer with battery 100% charged,it remains this way,
and connection is constant on .
Let me add ; with our old three 12v "add water" batteries and two
panels
I did not have above problem at all , and I was using computer a lot,
because I take many pictures and work on them .
Second problem; few days were not very sunny, and possibly we abused
consumption, and our gel batteries went down to 59% charge .
Now for two full days, better weather, and we almost do not touch anything, and charge is only 84% .
Questions, can be first problem related to our inverter which is only 750 W , will buying stronger solve the problem ? How strong should we have ?
Second problem, are our panels to week to charge this batteries
faster ? Will adding one more panel help/solve the problem .
We have room only for one more .
Or maybe everything together is something else , we are not aware off ?
And we have one more question .
Please be patient with us !
We want to buy solar refrigerator, cooler rather, 2 cubic food size,
consumption 60W (we do not know what it means).
This is also very expensive item for us, so we would be very thankful,
for advise, is it going to perform right with our settings, or
do we need to upgrade, and what batteries ? panels ?
People who sell this stuff here in Oaxaca, are telling us that everything is and going to be perfect . We lost our trust a little bit .
Please help, yes, we are pretty close to ignorant level .
We really try very hard to educate ourselves , but seems like our problems are sort of unique .
thank you very much eva
