This 'monster' Relay is a good quality heavy duty, high current on/off contactor. It is equipped with large connection points appropriate for large amount of current ... When you supply the coil with needed power the noise and torque produced is a proof that this relay can hold a lot, lot, lot of current! We have to take into account that coil gets warm after a while so ... this is another reason for the metallic plate - basement of this relay ... As you can see in the photo the coil consumes more than 0,6 A at about 12v thus when activated this relay needs a power of about 8 - 10 Watts that is a lot more than small relays need. These electrical and power characteristics make this relay more appropriate for start-up, DYI spot welding devices, or large scale - high power backup and solar panel applications. I am not sure it can hold 500A for a long time but i am also convinced that this can be used to start - stop and operate a 4000W (ore more watts) inverter like this one (https://www.banggood.com/Intelligent-Color-Screen-Pure-Sine-Wave-Power-Inverter-12V24V-To-220V-3000W4000W5000W-Converter-p-1243542.html?p=P828165195951201606J) with no problem ... SHIPPING and DELIVERY was very fast, once again !. NOTICE: For Power supply and measurement of test presented i n the photo i used RUIDENG DPS5005 50V 5A Buck Adjustable DC Constant Voltage Power Supply Module Integrated Voltmeter Ammeter (https://www.banggood.com/DPS5005-50V-5A-Buck-Adjustable-DC-Constant-Voltage-Power-Supply-Module-Integrated-Voltmeter-Ammeter-p-1062473.html?p=P828165195951201606J

These are really good mini solar panels. I bought 4 of them (this is 1st order of 3 of them) to make a DIY 10Watt solar panel (see photo below). With this DIY set of 4 on a sunny day in Greece i measured more than 8 watts during charging process of a 7,2 Ah, 12 V sealed lead acid battery. Measurement have been taken using Excellway® 20A DC Multifunction Digital Power Meter Energy Monitor Module Volt Meterr Ammeter (https://www.banggood.com/20A-DC-Digital-Multifunction-Power-Meter-Energy-Monitor-Module-Voltmeter-Ammeter-6_5V-100V-p-996111.html?p=P828165195951201606J) Shipping, delivery and packaging of the order was as expected, thanks to Banggood! Αυτά τα πανελάκια είναι πράγματι καλά. Αγόρασα 4 από αυτά (σε αυτή την παραγγελία είναι 3 πρώτα) και έφτιαξα ένα δικό μου πάνελ των 10 watt (δείτε φωτο) . Αυτό το πάνελ με τα 4 μαζί πανελάκια έδωσε μια μέρα με ηλιοφάνεια στην Αθήνα πάνω από 8 watts κατά την φόρτιση μιας μπαταρία μολύβδου AGM . Η μέτρηση έγινε με το Excellway® 20A DC Multifunction Digital Power Meter Energy Monitor Module Volt Meterr Ammeter (https://www.banggood.com/20A-DC-Digital-Multifunction-Power-Meter-Energy-Monitor-Module-Voltmeter-Ammeter-6_5V-100V-p-996111.html?p=P828165195951201606J) Η παραγγελία απεστάλη και παραλήφθηκε γρήγορα και σε τέλεια κατάσταση χάρισ και στο καλό πακετάρισμα με φύλλω λευκού αφρώδους περιτυλίγματος.
