## Questions & Answers

**Q: How accurate is the battery voltage reading?**
A: I have not put my meter on the batteries to test it I would be sure you got nothing to worry about

**Q: Is it safe to use the generator in my rv or the truck alternator when the solar system is attached?  do i need to unhook if there are other charging g**
A: Yes, it is safe for a couple of reasons. When the controller sees the voltage of the system is high (like when you have turned on your generator), it backs off and stops sending power out. I have several things attached to ur system - a generator, and alternator on the main engine, and a wind generator. No issues at all.

**Q: Is the li setting all i need to do to run lithiums or do i need to do anything else?**
A: Yes, that is the setting for Lithium. The individual settings automatically set the other settings optimally for the selected type of battery. 
In order to change any setting, you would need to select the custom setting, and then you would be able to set your own. However, even in custom setting, there are default setting already applied.

**Q: What software can I use to use PC with controller**
A: Relevant software has to be provived only if you have USB monitoring cables which will be connected to your PC, if you have bought MPPT with the cable, pls give me your email address so that we will send you our software, you may install to your computer. Thank you!

Relatively easy installation. Operates as designed. Keeping my solar battery well charged.

### ⭐⭐⭐⭐⭐ Best one yet
*by D***O on February 23, 2021*

So, I've had several charge controllers, all with plusses and minuses. This one comes closest to perfect. After trying out a Renogy which had issues, I found out this unit is basically a Renogy with better hardware. Even better yet, it uses the same serial protocol and cable wiring as the Renogy. This way, I could use the same monitoring software, which has been working flawlessly ever since. I use it in an all sky camera standalone application (pc, camera, cellular hotspot, battery and solar panels). I did shut it off during the recent cold spell, not because of the controller but the lifepo battery, which shouldn't be charged at low temps. So far, a few months in fairly hard winter weather, and this has held up as well as a victron unit which was my favorite. This one is even better, it has very high conversion efficiency (over 80% on most days) and so far reliable as heck.
