If you are worried about your refrigerator, then my point would be that if the battery is depleted, the fridge isn't gonna run anyway, so you might as well protect the battery. And if you don't open the fridge, the food will be just fine for several hours while you recharge the battery or wait for the sun to come back up!! Nope not worried about it at all, I was just voicing an opinion........ Hell I don't think about it but once a week if that much...... And I know way better than you do what my GE monitor top is capable of.......
Like I said my batteries have never been below 11.9 even after a week of clouds and rain, can you say the same? Oh yea I forget you still have AC power back up..... No need answering that........ LOL

I'll leave the fancy stuff to you and others............ They are not my cup of tea......... Or bottle of beer what ever you like better...... LOL

Wish we could drink one together sometime. I think we would have an f'n blast!!!! BTW have you ever made a YouTube of your setup? Might be instructive for lots of folks, including me. I was looking at some the old posts when you were putting it together - all the design issues, all the interaction with Renogy and other users. Would be fun to see all of that effort and the results, rolled up into some kind of story.

I am currently installing a (mostly) Renogy system in my garage and have 3 new (costly) Renogy AGM 100ah batteries. As I look at the specs for my Renogy Rover 30a controller and my Renogy 1k Inverter, I am concerned about limiting potential damage to my new batteries. I have always heard that pulling down batteries much below 12.0 volts for any period could seriously reduce the life or even ruin them. The Renogy 30a Rover Controller has an Over Discharge Voltage of 11.1 volts, and a Discharge Limit Voltage of 10.6 volts. The Renogy Inverter has stated shutdown when battery volts drop to less than 10.v and input less than 10.5v... These specs sound like they could expose my new AGM batteries to a high risk if the battery level drops due to more load and less sun than expected... I am new to all this but sure would like to hear some serious input before I proceed more... Jack (Tennessee) The Rover controller by default has the 11.1V disconnect, however it has a programming feature that would allow you to modify the parameters to your liking and even make it 12V disconnect if you would like. Normally, the disconnect would be based off the surface voltage and not necessarily the actual voltage of the battery, this would depend on your load. The inverter strictly uses battery power and will disconnect, so there would be no programming there unless you had our LCD inverter chargers which does allow you to program. -Renogy Team

Agreed very useful product. In fact we have discussed it before in a couple of other threads. But it still does not protect the battery from being drained by the inverter residual load. That trip point (unless you can change it) is usually around 10.5V, way below what I would want anyway.

Blue Sea LVD installed and working just as expected. Seems to be very good quality unit. Wiring the remote switch was a hassle but it is needed to program the LVD shutdown level. My total cost was $67 which seems cheap for the battery protection it provides.

I have sad news. One of the LVD modules that I previously recommended recently failed. It is one of three types I use. The others have been working well for years now. But this one, I can no longer recommend. I will be looking into some of the suggestions you guys have made here and in other threads. Fortunately, I have some good battery chargers, including the Lycan, which are able to restore a battery that hasn't been totally destroyed. I caught the over discharge situation early. So first, I re-charged each 12V battery (of a 24V string) independently, and now I am topping off the series string with the Lycan SLA charging circuit, which I have found to be pretty good.

I ordered a cheap 2-pack of the same unit. I will wire them in series until I find a better solution. I have another one in use that has been working for months without failure, but it is in a lower current, less critical configuration where I can catch a malfunction quickly. I like the Blue Sea, but so far I have only found the 12V version. Victron has a 12/24V unit, but its reviews are not as good as the Blue Sea. If I have missed the link to a Blue Sea 24V LVD, please hit me up!
