    Another one bites the dust ... And Another..

    AS the Queen song goes. Just got another call - system installed by a now non-trading concern, fried inverter, Samil in this case. The question is, what do you replace them with - Samil only had a 2 year warranty. Like for lIke? Something with a longer warranty? ABB / SMA ?

    Earthing for solar off grid system

    Hi All Planning an off-grid solar system and I’m pretty confident about most of it except for one thing - earthing.

    Do I need an MCB for a small inverter (120W)

    With a small inverter (120W), is it necessary to have an MCB for overcurrent protection? As the inverter can only produce 0.5A (say, 2A to be optimistic), it should never be able to melt those 1.5mm2 cables (rated 21A). Am I missing something important? We do need an RCD for sure. Just...

    Inverter replacements by manufacturer - invalidate warranty?

    I've noticed some manufacturers are replacing inverters themselves rather than sending the inverter to the installer. I wonder whether this could void the warranty for some firms?
