1) A wire from that specified earth terminal to a earth point- NOT to the copper water water pipes and preferably to its own earth...

The American Gigafactory puts Samsung Li cells into Tesla battery cases. Probably change as soon as agreements run out and new US models...

I am assuming there is a non-return valve in some jurisdictions that prevents legionella enriched warm water from returning back into...

Keep the original PWM charge controller for this panel. There would be insignificant advantage using a mppt CC at 16v when the mppt V of...

15v is the min stated for both Rovers in the specs. Even so, don't expect much charge out of a 100w panel on a cloudy day.

Not a Jeep Automotive Electrician, but- One battery charger - 2 batteries. The 3 amp battery charger isn't connected to the battery that...

Its rated at 4 amps. Googling brings up a wide range of quoted outputs from 1.7 to 4 amps. There is no heat sink on the bare board. On...

Probably means at 12.5v and above the battery will be still charged at the 13.55v rate rather than 14.4v (new cycle) which would occur...

I'll need further convincing to not see that these ponds are simply frozen when air temp drops below 0c just before dawn. Evaporation in...

Most likely 'Made in China' will be on any inverter you buy. No point paying for a brand name when one of similar specs is sold under...

War of the Currents 2020!!

We use rms for voltage measurement. 230v (rms). Switch companies do too. It is why heating elements AC or DC of the same rating have...

Very interesting. One question- How would the LV5048 react if the grid goes down with the micro-inverter activated since it will still...

For standard house panels the cost of repair exceeds the replacement wholesale cost. Those epoxy fixes on youtube look promising until...

Less than 2% voltage loss Yes! Wire is ok 18v 4amps 7metres A 10amp or above acdc switch will work at that low dc amperage.

A switch in one of the pv leads will do it. No issue with the current not going anywhere with that size panel. Even though the unit is...

The ratings for switches of the same amperage always have DC V much lower than AC V example-...

An option is to leave the hws intact and place the dc element at the inlet, sloping up to use thermo siphoning for heat transfer...

Solution to 1st problem- sudo shutdown -h 02:00 Solution to 2nd problem- I cheated and used a variable PSU set at 13.1v with some...

pv ohms is 2.7ohms From the table provided by z80 the closest element with this resistance is the 1000w/48v with 2.3ohms - This...
