Hi,
We now have a second 12.V 105A "Deep Cycle" battery attached to our 330 Watt solar panel.
After leaving the inverter switched off during the night, we had full sun between 7am and 9am ( we are near the equator, in Nicaragua), and the charge controller went up to 14.7 . V.
We then plugged in our 70 Watt ( Inverter / Linear/ Compressor) fridge, and the Charge controller dropped straight away and showed 12.7 V.
How should we interpret these numberS? If the battery was showing 14.7 V, doesn't that mean it had been charged to that amount and therefore why does it drop so suddenly to 12. 7 V ? Is this normal ? I mean, for the number to drop so quickly from 14.7V to 12.7 V ? Should we leave the fridge plugged in and just wait for the number to go up again?
Since starting this post, it has gone up to 12.9 V.
We also noticed the number drop when there is a bit of cloud overhead.
Sorry for what must seem dumb questions to people with more knowledge, we want to learn,
Thanks, Joe and Maria.
