Hello.
If I have on the roof ten 250 Watt solar panels for a total of 2.5KW; and series/parallel wired to supply 115VDC output to a heating element inserted in my house HVAC duct (day only use)
The heating element is rated 5 KW at 230VAC (~22Ω); when fed by 115VDC from the panels will heat not glowing red.
If I split the heating element to two 115VAC paralleled elements instead (~6Ω), when fed by 115VDC from the panels, will glow red.
Which arrangement will heat the house more; the heating elements in series or in parallel ? Seems there is a flaw in my thinking ?
