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.

This is 2nd order of 1 more item to complement the first order of 3 first items. I bought 4 of them - in total - to create a DIY 10Watt solar panel (see photo below). With this set of 4 panels 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) After a test of 5 weeks they proved to be really good and reliable mini solar panels. Shipping, delivery and packaging of the order was as expected, thanks to Banggood! Αυτά τα πανελάκια είναι πράγματι καλά. Αγόρασα 4 (σε αυτή την παραγγελία είναι το 4ο μετά τα 3 πρώτα) και έφτιαξα ένα δικό μου πάνελ των 10 watt (δείτε φωτο) .

Και αυτή η παραγγελία απεστάλη και παραλήφθηκε γρήγορα και σε τέλεια κατάσταση χάρις και στο καλό πακετάρισμα με φύλλα λευκού αφρώδους περιτυλίγματος.
