With no load, you say the voltage is 19 volts - that means your solar panels are not getting full sunlight to produce 100 watts. The inverter will waste a good bit of power in converting the DC from the solar panels to AC. It would not be surprising if the inverter wasted as much power as it puts out - your 33 watt lamp would then require 66 ...
Panels showing 18 V low or no amps
At that time I just checked each one''s no load volts, and all were 18 plus to 20 volts. Now I''ve hooked them up to a charge controller and in bright sun with a battery that can accept a charge (12.9)- all show 18 v plus - …
No Amps on charge controller
I ran a load on my solar setup and discharged the battery to 11.9 v. However, my solar reading on my charge controller still shows no Amps to charge the battery. I disconnected all my panels and reconnected them and made sure they were tight connections. Earlier posts in this thread show my wiring.

All You Need to Know about Amps, Watts, and Volts in Solar
As watts, volts, and amps are explained by ohms law the output of the solar panel which is watts is calculated from amps and volts. According to the formula, the watts or final output remained constant when volts decreased, and amps increased respectively, or volts increased, and amps decreased respectively.
Solar.... getting volts but no amps????
Sometimes the load is more than the panel is producing, so the net is a negative number. Likes: Rick D. SycloneDriver. Jul 23, 2009 867 Beneteau 31 Oceanis Grand Lake, Oklahoma Jul 19, 2020 #7 From my experience under normal conditions a solar panel will produce 75% of its rated power. ... first solar panels are rated at the …
Solar Charge Controller Basics
A charge controller, or charge regulator, is basically a voltage and/or current regulator to keep batteries from overcharging. It regulates the voltage and current coming from the solar panels going to the battery. Most "12 volt" panels put out about 16 to 20 volts, so if there is no regulation the batteries will be damaged from overcharging.
ISSUE: (SOLVED) Low Voltage Output from MPPT
I have issues with my MPPT that does not output sufficient voltage for charging. Solar panel seems to be working fine, but the MPPT does not up the voltage to more that 12.6-12.8.
