BG353854131 15/03/2021
It is a good and versatile product. The three sections are wired in parallel, so if a shadow happens to fall on one or two sections it still yields 2/3 or 1/3 of power. On a sunny early spring day (at 20 °C, 650 W/m2) at a maximum power point (MPP) I get 75 W, which is very decent. The wires that come with it are quite thin, so the longer 3 meter wire loses 5.7 W of power at MPP 75 W, which would be about 10% of power at 100W - so it might make sense to replace it with a thicker wire when feeding a power pack. I have modified the shorter wire with crocodile clips replacing them with MC4 connectors, so that a regular small MPPT solar charger can be attached for more efficient charging of a car battery.

Q: in diode mode does it beep on shorts? does it beep with leads shorted in diode mode?

gevraagd door BG141338481 op 2022-06-09 01:50:57

BG353854131 In ohms mode it is selectable, beeper can be enabled or disabled. In diode mode it does not beep.

Arrived in less than a week from CZ, in good condition. Works as advertised, it's a very decent DC load for the price. Supports MODBUS-RTU protocol over RS485 or RS 232, up to 115000 bps (defaults to 9600) , which is the main motivation for my purchase. Modbus registers are documented in the accompanying manual. The banana sockets are a bit too wide for a good contact with regular banana plugs, one should use spade or ring terminals on a connecting wire. The four screws on the back are electrically connected with a plus terminal, which can be a safety hazard. Also the metal chassis is not connected with a safety ground. So the device does not meet the Low Voltage Directive for a CE mark, and needs to be used with care (or modified, which is not difficult). Overall, a good product.

Q: Is it possible to use it while charging?

gevraagd door rafaelsans op 2021-11-11 02:49:19

BG353854131 In principle yes, but it is of no practical use. The compressor's power demand greatly exceeds the small power available through the USB charging socket, so it makes not difference if the pump is connected to USB or not when pumping for a short time.

Q: can it work directly from a solar panel which has 91 volts on VOC?

gevraagd door BG141121117 op 2021-05-26 11:30:50

BG353854131 No. It is clearly stated in the specs that the voltage range is 10.8-30V or 20-45V (depending on the model chosen).

Very fast delivery, arrived from CZ in just 3 working days (plus a weekend), thanks! Looks solid and well built. I still need to figure out how to drop my open circuit voltage of 49 volts of a 72-cell solar panel to below inverter's upper limit of 45 V, which is a bit on the low side. Currently it tries to start (green LED on for few seconds) but then fails with a red light, probably due to its overvoltage protection.

The device is well made, packaging is good. Considering the low cost it is a reasonable device, although user experience is not very good: user interface and web browser is quite slow, and playing HD media (either from Youtube or streaming TV) is stuttering at times even when connected over Ethernet, even more so over WiFi. Stability is not very good: exiting some apps or shutting down locks up and a power-cycling reset is needed. Simple Android apps work well and it is good that apps need not be installed from Google play store. A mouse and keyboard can be connected over USB, also an external disk.

Q: does it have built in bluetooth and does it have microphone input

gevraagd door paris op 2021-01-07 10:20:44

BG353854131 Does *not* have bluetooth, despite being mentioned in the specs. No microphone as far as I can tell. A mouse and keyboard can be connected through USB.

Package arrived in one week from CZ. The packaging is very good for transport, double cushioning. The device looks good, is well built and works as advertised. Tested with a candle flame and the oxygen is definitely there :) Controls are simple to use and pretty much self-explanatory. Placement of labels on the remote control are a bit confusing (labels are between two knobs), but no big deal. Noise is acceptable. Specs does not say if turning on anion emission produces any unwanted ozone, so I prefer to keep this feature off, just in case. Good instructions in multiple languages. Overall, I'm very satisfied with the product.

A decent heat gun station for a reasonable price, works well. Temperature checked with a K-type probe and a lab instrument and is close to the setting as shown on the display. The air blower is fairly quiet (speed is adjustable) and its sound is not unpleasant. The most annoying thing is its very loud beeper, which sounds with key-presses (and auto-repeats), on startup, and when the set temperature is reached. I tried to muffle it down covering it all around with hot glue, with limited success - it is still too loud. It would not be easy to non-destructively remove the component, as the back side of the PCB is sandwiched with a display board. Overall, I'm happy with the purchase.

Nice measuring device, good display, works very well. Good instructions in five languages. Could be very useful in these coronavirus19 times as an early warning device. I'm happy with the purchase.
