Solar Controller

[Burge]

I have a Burstner Harmony 690g with a Teleco SPC 10/1 Solar Controller, not sure if is working correctly as no LED's on the 25% to 100% Gauge light up, the Red Power Outlet light is lit . Having put a Meter across the input from Solar terminals in sunlight I have around 24v on output to Batt 14.2 so think it is doing it's job but don't know why the Gauge Lights do not illuminate. Do I have a problem thanks Chris.

Another good case for an energy meter with a shunt.

Gives confidence in battery charging (and discharging) whatever the leisure battery technology.

Even better with a physical display.

Anyone got any info please

I think No problem. you have a fully charged battery so charger is thinking what do you want me to do , nothing , so it does xxxxx.
I i aggree a physical display of SOC is handy
for Lead acid i used

for Lithium i now use a Victron BMV712 not a smart shunt for 2 reasons
1 display easy to see (even if in cupboard) no phaffing about with phones.
2 The 712 has a relay that can be triggered by voltage, temperature, SOC etc to do whatever use you can think off /need. I use mine to trigger charging based on SOC (relay turns on a SSR)

If you mean info for leisure battery energy meter, then I use an NDS Energy Meter from RoadPro.

It does the job nicely - and has a physical display - no messing about with bluetooth.

Don't think I explained correctly ,when Leisure Batt Voltage drops to say 12.75 or lower should I see the Gauge 25% to 100% light up ,as I am not. Even when Fully Charged Don't see the 100% light up all I get is the Red Power Outlet lit ??

just a quick check I would do. With a meter, the voltage you see across the output terminals of the controller should be the same as across the leisure battery? If not you have a problem.

It is me that did not explain correctly.

What I was trying to say is that reading voltages and lights is far from the best way to see battery state of charge or whether a charger is working - no matter what make the charger is what lights it might have.
