Load control Programming feature of the EPRC solar charge controller AVI

I see another youtuber testing this unit which I've been using for a few months. The programmable load control feature is great. The controller uses your solar panels as a photosensor to turn your lighting or other loads to go on/off. A few minutes after dark, the controller will switch on the load automatically. You can program your12v lights to be on from 1 to 13 hours. The controller is only 10amps and goes by other names also. The unit is $30 on Ebay. In life, sometimes you overpaid, get a bargain and sometimes a real steal. Well, $30 for this unit is well worth it for me.

Hi!

I've a question about controller.

I would like to know by you, if with this specific model (or similar see in Ebay 10 A) , the process of charging-descharging it's well managed. In the specify , I would buy this economic controller, but with features:

- I would like that if it is fully charged the connection is disconnected from the battery...

- When the battery is fully discharged to go off, take off the load

it's possible with this economic controller??

thank you so much!

@mrsirio187 I believe it will do all those things you described although I have never had the battery discharged so much the load needs to be disconnected. I use the timer function to turn the load on for a few hours only. The manual says load disconnect is 11.1v. I don't think I'd want my battery to run down so much. The normal charging is good so far. I've had this charger for about 2 years.

how many watts is your panel

how many amps of battery u use

how many watts ur load is

how long ur battery last using inverter.

thnkz.

@SuperFeejay I use a 15w Sunforce panel to charge my deep cycle battery Only use 3,4 amps per night The load is 3w or so LED lights. I don't use the inverter to power the leds as they are wired for 12v and powered directly by the battery. My battery is 125 amp hour so you can use half of that each time before recharging. My inverter is used for backup only.

ive got a like that charge controller for only $24. nice setup what size of wire you use?

[wtam69]

@SuperFeejay The charge controller is much cheaper now. I think they sell for $17.50 on Ebay. I believe I used 10 or 12 gauge wires for the charge controller and 6 gauge wire from the battery to the inverter.

@wtam69

thank you! :)

@yuandrew Thanks for the info. This controller is cheap with an abundance of features.

There is also about a 10 min delay in modes 0-5 between it detecting "dark" (PV voltage going under 3 volts) to when it turns on the load; that is to make sure it is actually dark out and not because a passing object or cloud shaded the solar panel. "Test" mode bypasses this delay and turns the light on immediately when you cover or disconnect the solar panel.
