Hi had a quick look on the internet and found this.
C & S Solar are pleased to announce that we are offering the latest range of PV Enhancer connection units – the BOS Solar + Plus. By monitoring the incoming supply voltage, the BOS Solar + PLUS allows the Solar PV inverter to compliantly stay in circuit for longer, preventing nuisance over voltage shut down.
However, WARNING, when I clicked on the link to find out more my virus software went crazy and stopped a threat.
Not only are they trying to con us, they are also wanting to put some kind of trojan virus on our equipment.
Scum bags, all of them. I am glad I have a call blocking telephone so don't get those calls.
Stay safe out there in more ways than one.
Regards, Howard.
