I measured my dawn to dusk security light in daylight, it measured 0.5 Watt (spec doesn't list off, only on and that is 30watt). The shop light on measured 53.5 watt (spec says 60).
The issue I'm running into is the inverter. the specs says no load is 0.6 watt. This doesn't seem to be the case. I haven't measured it, as i don't have a clamp meter. Even with the lights unplugged with the inverter on, i can watch the battery voltage drop on my multimeter - in a few minutes (maybe 5) it does 0.2V.
I found a few websites andv you tube videos the show other inverters being around 5amp no load when specs listed .<0.6.
Even with no sun, the pwm controller with 100W panel was able to recover the used voltage in a few minutes (little more than the inverter was on).
I'll try to see if i can find a lower Amp no load inverter. And I'll have a clamp meter tomorrow to test the inverter with no load and with the security light at 0.5watt.
If anyone has a suggestion for inverter, I'd appreciate it.
Thanks
Dan
