From the product description it was already clear that this panel could never supply 150W. Short circuit current multiplied by open circuit voltage is NOT the correct way to specify the power of a solar panel. After testing myself on a very clear and cool day by putting two panels in series and measuring with different methods I reached a maximum of 175W. This is for two panels, so 87.5W per panel. I measured while charging batteries with two different MPPT solar charge Controllers and both gave the same result +/- 2 W. For the price the panels performance is still okay, just don't expect to get the performance indicated. What I also highly doubt but obviously won't test is the "waterproof" part. I expect the panels themselves to be absolutely water-resistant but can't image the same for the junction box with the output connections. While it is inside the bag on the back of the panels I doubt this is waterproof for more than a few minutes if light drizzle. You better don't put this permanently outside but just set it up temporarily when the sun is out. I haven't contacted the seller as I don't expect any improvement to be possible but I more or less got what I expected.

I really hope I received a faulty unit but I don't think so. generally the product looks good and also the AC output works fine. My problem with the unit is that it's not possible to charge it from solar. Contrary to the manual that states to use a 18V solar panel for"best performance" the unit will not charge at all at such low voltages. after quite some testing with different solar panels and a lab bench power supply I can confirm that the unit will only charge when the input is higher than the current voltage of the battery. As the nominal voltage of the battery is 22.4V and the charge voltage is 27V this means you'd need a solar panel with such high voltage. On the other hand the manual states a maximum VOC of 28V (30 in another place). Unfortunately unless I received a faulty unit is impossible to charge this unit from solar at least without the use of an external charge controller that can supply a steady 27V. Just to confirm, yes, I did use the Anderson connection specified for solar charging and the unit does charge fine from the supplied wall charger. it also charges fine from the Anderson port when supplied with a high enough voltage from the lab bench power supply. I really hope Banggood can provide a good solution for me as otherwise this seems like a really good product.

lernfaehig Kann das Gerät AC ausgeben während es mit Solar lädt? gibt es genauere Specs zu dem Solar Eingang? Gerne auch in englisch

good, I charge it with usb c pd 3.0 trigger + Baseus 65w charger. Be careful, no overpower protection on the AC Output, only the Voltage drops to zero.
