pic of 3 wire strand is what came with rover 60 also a green block wires connect to on cc side i am just not going to use them cc seems to be working fine without them but the voltage is not accurate My 60a commander CC didn't come with those wires..... |

Admin the 60A rover is new and although YOU claim not to send a voltage sensor wires, one can certainly add them cuz the port seems to be there! let's believe the OP that says the other end has "wires" as in 2. Has it been deactivated for Renogy? the "Battery voltage compensation interface"? SRNE 60ANormally they should not be coming with the sensors. We will be checking if this is reflective of new inventory. -Renogy Team |

  his is what i have been talking about i have figured it out for myself i can not can not understand why that no one had any idea what i was talking about i am not happy with renogy they just rebadge items they have no clue about will never buy another product with their name on it again bad docs bad support bad company left me a bad taste about them but thank guys for the imput |

I understand your frustration with Renogy........ I know most of what I know now is because of Renogy lack of help when I first started in solar...... But I really like there products....
Just think of it as a learning curve........

thanks tattoo for your input and everyone else who tried to help
i think some 60 amp rovers must of came with wires and others were left out i am better now lol
but it did really did grind my gears and i am sure we are all been there on time or another and the system is running great that"s all that matter and i hope i haven"t left a bad taste in anyone"s mouth again thnx

As the op states, there is a battery terminal that is located on the Renergy Rover 60A that is described as the "Battery Voltage Compensation Interface" on page 09 in the manual. It is item number 15. The box included a wire set with three wires.
My system does not charge the batteries any higher than 80% using the Renergy Rover charger. I have disconnected the batteries and checked that they will charge to 100% using a deep cycle charger. They hold the charge. The Renergy Rover 60A charger claims that it is charging to 100%, however once the sun has gone down, and without any load on the batteries, the Renergy Charger claims that the charge is only 80%.
Another clue that something isn't right is that when the batteries are discharged to 65%, the Rover claims that the batteries charge to 100% in a very short amount of time. Roughly an hour's time.
My set up is 600 watts at 90v using three panels and 2 6v SLA batteries at 225ah per battery. I am guessing that the Renergy Rover is not correctly sampling the batteries. Would the battery voltage compensation interface fix this problem. If so, what is the correct way to connect it?

SOC% is useless it's shouldn't even be there........ It means NOTHING.............. All it does is confuse people....... See it worked........... |

tattoo bupkis. True, it is abstract. My general estimate of the charge that is left in the battery set is extrapolated from the only values that can be read from the terminals - Voltage, and from a comparison over time. Thus, at ~13.2v I get a 100% reading and at ~12.3v I get a 52% reading. If we round .9 v to 1v then we can assume 11.3v is .00 percent and the range is ~2v. Not highly accurate but good enough. If 2.0 = 1.00 percent then .80 of 13.2 is ((2.0 x .8) + 11.3) which is 12.6v If the voltage value at 100% is the battery at 13.2v then that can be used as the basis of 1.0 . If the charge status shows 100%, and holds 100% after the batteries are disconnected from the charge source, IE the solar panels, then it is a fair estimate that the basis is 13.2 volts. 13.2v as 100% is fair. The batteries will read 13.4v with 0 load. I'd be happy if the the charger would provide a more accurate estimate but there is no free lunch in physics. I'd be happier still if after the sun went down, I had 13v remaining. Is there a way to adjust the charge cycle so that at least 90% of the battery is left after daylight. My guess is that there is some conservation built into the Rovers software to extend the life of the batteries. But at $500 for a set of batteries vs thousand saved on power over that same time period, Then, there is no issue with replacing them every three years.

These controllers are not amp hr counters in / out which a decent battery monitor is.
They came up with some algorithm and over time you may figure it out!
let us take a 100 ah battery and charge it @ 5A another @ 10A another at 20 another at 30, the voltage will be different for each as it charges up to 14.6v set pt but each will read the same % as the same voltage which is bogus. The faster charge needs longer boost. And with solar ya get low amps till the sun is good then good amps but then there is clouds etc. IE there is no correlation. Is the 2 hrs boost enough? Is float really 100% (not always).

Somehow, the advice on this forum sounds similar to asking the troll under the bridge how far a North African Swallow flies in the fall migration. I'll give $5 to the one who can answer which movie that question came from.

It sounds like your understanding now why I don't bother even having any of those LCD readings? To me, it's a waste of time....... Now if you don't have much to do or you think it's cool to look at your phone or what ever device you are using like so many these days do.... Have at it, it doesn't bother me at all......
All you need to know is the amount of watts your using at night and the state of charge in volts not % your batteries have in the AM when the sun comes up...... You know like 12.0........ That's an example...... That's 1/2 of what matters.......
Also what your batteries have in them at sun down doesn't matter either, just as long as they got to 14.2 some time during a sunny day....... And that 14.2 depends on your battery type you should go by what type battery you have......
That's all that really matters at the end of the day, Or morning...... LOL
