My first Off grid solar system

Cansno, how would you add batteries to an already used battery-bank?

You don't. New batteries will be quickly degraded to the level of the existing batteries. Best to just wait till they fail, and then replace with a proper size bank. Solar is not for folks with a tight budget and unrealistic expectations.

I realize that totally. That's why I said in my post, to add if existing ones are in good shape. I added an extra bank to mine a year after system install. After a month or so, all balance out to 1.265+. Except for the hickup we talked about in our other post (which was my fault), they appear to be on the way back again.

12 volts 3 panels (100 W’s each )In parallel .This will give me 12V @300 W connected to a 40A EPEVER Tracer AN Series charger controller and also I will do another 12 volts 3 panels (100 W’s each )In parallel . To a second 40A EPEVER Tracer AN Series charger controller. Both controllers will be connected to the same battery banks . The reason I am doing this If needed I will be able to add another 200w if needed. Also there should be less stress on the controllers by using 2 controllers than 1 80 A controller and if one fails the other will still work even if it is half the charging temporary

I purchased two Renogy 100 watt panels to charge a Goal Zero Yeti 1000 solar generator. So far it appears that we will be able to run the freezer by charging during the day and running the generator at night

So I am curious about the battery Ah rating in the Yeti system. With 2 100 watt panels you may only get about 10 charging amps which would be ok for a battery between 80Ah & 120Ah.

Less than 80Ah might cook the battery and more than 120Ah may not properly charge it.

Hi I am a new to forums and this site. Can anybody help me get started . I would like to post a question. I assume post Reply would mean to reply to someone post. . I see the original post is in grey shade and the reply is in white . Is this correct.

From an internet ad of a local supplier here.

200Wp panel running a freezer 24/7 365 days a year with less than 100Ah battery (1045Wh total energy )...wow...

sounds really fantastic

Buy it and try it out ! it might work under perfect conditions, but in real life, I suspect it will fail 99 times out of 100 random installs

I would say that falls under the "fantastic" area. I seriously doubt 200 watts will run a freezer and a 100Ah battery will be quickly drained before the night is over.

If the freezer is very efficient and the inverter can handle the starting requirements of the compressor motor you might be ok but most freezers need a lot more than what you propose to run it 24/7 365 days a year.

How long ago did you purchase Yeti 1000 and runs a freezer with it ??

Hey guys, can you point me to the correct type of fuse to install between the battery and inverter and would i need one between the inverter and load? Thanks.
