Hello everyone,
Just wanted have a much better explanation about this. as well wanted to know if it’s normal cause something seems not right.
Have a 500Watt Solar Panel, on direct head sun around 1:00 PM (Haiti Time) we have plenty of sun. I know already that i won’t have the full 500watt, but at least i should expected to be around 300watt or almost 400watt when we
GREAT SUN.
the last peak i get from that great sun is 230Watt.
Can you give help me with this… I know i should get more wattage at great sun… not expected to be 230watt max from a 500watt Solar Panel…
also need to downgrade, IoT, ARM, DSP as well… i found out it worked much better the last i just clicked update for these two options… the BMS is fine… these three needs to downgrade to it factory state…
here is my serial number : AC1802439000459174
The only way to know a definitive answer is; when you see you are getting 230 Watts, is to check 2 input values.
The voltage on the input cable as close to the power station as you can with a multimeter.
With a clamp Ameter, check the amperage on either the positive or negative input cable also as close to the AC200L as you can. Then multiply V x A = W.
Failing this, use a DC power meter inline , which will give V, A & W.
The first thing to check in your scenario, as above, is checking panel output. I don’t have the AC200L, but, on my smaller power stations, if the voltage is below 30V, they throttle the input amps from 10A to 8A. Yours is a 15A max input and I don’t know what, if any, voltage throttles input as the max Voc is 145VDC.
Edit your post with @BLUETTI_CARE at the begining, this will tag the official Bluetti to respond.
Hi @JavaScript_t, Based on the information currently available, we believe this issue is unrelated to the firmware update—downgrading the firmware to the original version will not resolve it.
Could you please try using this solar panel to charge another power station and see if the result is the same?
We consider that this may be related to the solar panel’s own conversion efficiency, as the input voltage is also not high. Please try adjusting the angle of the solar panel, wiping off dust on the panel surface with a clean, dry cloth, and avoiding any shadows. We look forward to your feedback.
Thank you to @Mandp for your concern and helpful insights.
