Over powered solar panel watts/amps.

[Rogue]

Is there a way (or is it safe) to use a single panel that produces more watts then the documented limit on a power generator? ie the system is rated for 200w solar input but the panel is say 250w. do these machines throttle the extra watts?

.... same question for amps.

It depends on the machine.

I presume you mean solar generator but are keeping the brand and model and specs a secret.

As long as you do not exceed the Max input voltage aka Voc then you can Overpanel by a reasonable amount with any excess at peak being wasted.

Watts and Amps are not hard limits like Max voltage.

Ok thanks. Not a secret just haven’t pulled the trigger yet on one. Most of the sub 100ah models only handle 200w except for the Delta which takes 400w. Thanks though. I wasn’t sure.

If it does not list the max input volts, i would scratch it off your list.

Is there a way to regulate the Volts/Amps between the panels & the solar generator?

I have not heard of a practical way to actually regulate volts/amps.
The best would be to buy panels that match your solar generator...or vice-versa.

Voc is the voltage to use to calculate max volts input to your generator.
If the combined Voc ( open circuit voltage) is under your Max Input then no need to regulate.
Vmp is the voltage when making power and will be less than Voc.

There is no need to regulate Amps and you want to maximize Amps for more watts.

Here is a panel and an generator example very close but the panel looks too much for this solar generator it’s the bluetti 50s

(Hobo on YouTube over powered and the machine shut down at 45v)

BLUETTI AC50S Portable Power Station | 300W 500Wh

Keep your gears running, indoors and out. BLUETTI AC50S portable solar generator is designed to power drones, camera equipment, laptops, phones, and more.

www.bluetti.com

...
It must meets:

1)Open Circuit Voltage (OCV): 12-40V/Max.10A, Max.120W (DC7907 to MC4 Charging cable is included)
2)MC4 Connector

Tips: make sure the total OCV (open circuit voltage) is no more than 40V if you connect several solar panel in series!!!

Yeah the Voc of that panel is 43.6V against the ~ 40V max input of the Bluetti 50S
Also panel Voc raises as temp decreases so that is way over what the Bluetti can accept before turning off with an error message.
