This is something that may interest Glort, one shown in the image is not mine but same model

Lister SR 115 with a history.

Got it figured, but having trouble convincing the IT people who maintain our internet service.

The ISP installed electronic gear inside the electrical utility building that services the bin yard when switchgear for the solar changeovers take place it creates a ripple which in turn creates an electrical magnetic storm inside the building.

Today sunrise 5:44 am ↑ (53°) with this mornings internet interruption at 7:43:28 a.m.

Looks like the solar array storage battery's need recharging before dumping back to the grid, in the evening those storage battery's are depleted within minutes and the evening internet interruption coincides with sunset.

Phases don't influence the output, they just do it that way to stop pushing one phase too high relevant to the others and to avoid pumping too many amps down one line.

Depending on the location of the array, in summer I'd guess 3-500 Kwh a day.

The EMI on inverters here is VERY low by regulations. Many work off US standards so I would be surprised if yours is much different.
I would also assume ripple is pretty low as well.  It would have to be throwing some pretty significant radiation to influence your wireless internet from 1.5  miles away.

How do you know it's this causing the interference problems?

Our ISP has a repeater mounted on the high point and the inverter for the array resides inside the white building.

Internet outages coincide with sunset and sunrise, I suspect it has something to do with the private system being switched onto or being disconnected from the grid.

Glort the solar array is 3 phase, how many kw do you figure this set up is capable of producing during the longer days full of sunshine.

Refrigerated air dryer but your most economical solution would be to hand a burlap sack laying against the current dryer then trickle water down the burlap to make a swamp type cooler.

A boat used in salt water will use a sacrificial zinc anode to protect the metal parts from premature corrosion.

Boats berthing at a marina should use a "shore power isolation transformer" while connected to shore power otherwise any boat in the marina with poor or non existent anodes connected to shore power will suck the life from your boat via electrolysis.

Boats used in fresh water use either a sacrificial aluminum or magnesium anode, the domestic hot water tank in your home will also have either type of anode factory installed.

Sacrificial anodes should be checked periodically and replaced as required. And this goes for those of you using heat from your engine to heat water for domestic or other use.

Install the appropriate anode it will add years of life to your engine. Liquid cooled engines often suffer from cylinder liner porosity caused from electrolysis, inhibitor's added to coolant can slow the process.

The list below, the electromotive series of metals, as a precious metals refiner the list is of importance to me.

For instance if I had a multi species liquor and only wanted the precious metals recovered from it then I would use scrap copper. All the metals above copper would be unaffected and remain in solution. Bla Bla Bla.

Each metal on the list above another reacts with all those below it and none above it, having basic knowledge of the series will help you understand galvanic corrosion and how to prevent it.
