Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?Include you power supplies and panels.
Hi,Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?Include you power supplies and panels.A picture is worth a thousand words.Thankes.. Tom....
No real need in this case is there. It's a standard solar charge controller with standard connections - Solar, Battery and Load - nothing difficult or special
Question: Would it be safe to connect the Arduino directly to the 12V battery (instead of to the malfunctioning 12V output of the "charge controller") or would the attached PWM charge controller have any side effects that might be dangerous to the Arduino based device (whatever the "charge controller" feeds to the battery to "recharge it" would obviously also be input into the Arduino..)?
Sorry but your circuit is just about unreadable.
Isn't the 12V Output of the charge controller already connected directly to the 12V battery?Please hand draw a diagram showing PV, Solar Controller, Batteries and Arduino controller, with pins labeled.A picture of your project would help.Do you have fuses on your battery?It sounds like your battery is not connected to the Solar Controller output.Do you have a DMM to measure some voltages?Thanks.. Tom..
This is the live output from my system using an MPPT controller and 40W panel with a 12Ah SLA battery. I have found that if the solar output goes above 16 volts it reports that the battery is full even though it may not be and is still pushing current into the battery (trickle)
Hi,What voltage do you measure on the LOAD terminals.It sounds like you have lost the load to battery connection inside the charge controller.That controller has a few timer functions, check that one of them is not involved in disconnecting the load terminals from the battery.Tom..
