Would 1/20C of a 200ah battery be a 10 amp charge?

Sorry for lack of reply. I've been on the road for the past few days. I've attached a copy of the battery spec sheet. It makes sense that the battery is discharged to the point where the controller does not recognize it. I've got a Renogy Rover 40A controller and was only running a 12/24 DC...

More lessons to be learned the hard way. Well, I committed the ultimate lithium sin. I forgot to turn off my new inverter when I got up and I went off for the day, leaving my 5,000 btu air conditioner running. So, my converter says the battery is at 0.2 volts and my panels are providing 62.7...

Click "Set". The first time I did that, it didn't save and returned to the default settings. I re-entered and tried a second time and it saved. Thanks for all the help. My apologies if I'm a little slow with this stuff. I'm definitely a "newbie" at solar. If I was just wiring a hot rod from...

Or, do I change from USER to LI?

This is awesome! I didn't realize it, until I opened the BT manual that you attached, but the app I had downloaded was an impostor called DC Home. That was the reason why I could not find half the settings you had previously mentioned. Now that I have made all the changes, is there a "save"...

I finally realized that the "User" mode is accessed through the battery type selection. Got the parameters changed. Using the buttons on the unit, I did not see the ability to set a Boost Duration. I did see that listed in the BT app settings, however, I have yet to figure out how to use the app...

From the BT app, I went to the settings screen. Correct me if I am wrong. If I have selected 24V as the system voltage and the current setting for Boost is 14.4V, that would give me a 28.8 Boost. If so, I would need to change the Boost voltage to 13.75V in order to achieve a Boost setting of...

Need some help with a Renogy Rover 40A. I've got a 24V 200ah LiFeP battery. I'm only running 24V DC along with a step down to 12V DC. The 24V powers my fridge/freezer and a small 24V A/C. The 12V powers phones, laptops, fans, and small appliances. No 110V AC, so no inverter. I managed to set the...

I ended up going with a 24 volt system. My two 24v/200ah batteries are finally arriving today. I connected the panels in 2S2P and ordering a Renogy Rover 40 amp controller with bluetooth. I appreciate the input on the breaker/switches. I'll add them to my orders. I've gone to 12 or 24 on...

I have a new question. I want to install a disconnect switch between the panels and the controller. All of my pv cables are 10 ga and I'm installing a 100 volt / 40 amp controller. Would a 40 amp double pole be the correct size?

I ended up buying a 47 quart that is 12/24 volt for around $280. It's a dual zone unit. I really like that it has a removable partition that gives me the option of running the entire unit at one temp, or one side as a fridge and the other side as a freezer.

If I wire these panels in 2S2P, would I be correct in assuming around 60V at 16A to the charge controller during full light conditions?

Got it! I was thinking along the same thing, mainly because I'm going to be stopping to set-up in places that I've never been to. So, not knowing what the shading might be, the 2S2P should cover the possible shading issues. Just needed to hear it, since most of this is new for me. I've done...

I'm going to stick with 24V for all of my appliances, with the exception of one or two 110AC items that would only be used for short intermittent periods. With four panels that are 240 watt, Pmax 29.54 volts, Pmax 8.13 amps, do you think I should wire them parallel, or series-parallel for...

kenryan, Are you referring to my question about keeping the two systems separate? My concern is my vehicle 12 volt system that provides starting and ignition. So, you're saying I would run my starting and ignition off of my 24 volt house system by using a converter to 12 volts?

Hey, I've got another question. If I run a 24V house system and a 12V vehicle system, wouldn't I want to keep the two totally separate? For the house system, I'm thinking that I would need a junction block for the positive leads, but also another block for individual negative leads, too. Could I...

Well, it is a passenger van with the rear A/C unit. I'm not expecting the Zero Breeze to cool down a hot van. If it can maintain an already cold van and keep it relatively comfortable during the night time hours, it will do just fine. It's also a standard roof (can't stand up in it) with...

Thanks for the input on this. I think you're right, the 110V fridge is going to have to go, in favor of a 24V unit. Makes sense, since the air conditioning and fridge would run pretty much full time. I could look at a 24V TV and 24V water pump since I haven't made those purchases, yet. I'll do...

Okay, so this is my first post as a new member and I could use some help on deciding what voltage battery system to use for my house battery. I am building a camper from a 2007 Ford E350 passenger van. I intend to create an off-grid system that will sustain us for up to 5 days in remote...
