physical size of solar panels

Perry,

You are rarity. The wfco converters rarely get to a boost voltage. 21 volts may indicate an electrical failure inside the "box".

Ya Think! ;)

I'm not the only one with a WFCO that went haywire. Last winter after much surfing I found one and after reading about our experience, another contacted me who had the same issue. The crazy thing is, the 21 volts was intermittent.

Our original WFCO has been recycled. A member of another forum gave me their working WFCO for the cost of shipping. They had just purchased a set of lithiums and purchased a Progressive Dynamics charger.

Since I pulled the reverse polarity fuses last February we haven't needed the charger. So far solar has kept our batteries full.

The new WFCO unit is installed and appears to work correctly, but now the reverse polarity fuses are pulled so it only converts. Perhaps someday we'll need the charger portion, so I'll just install the fuses then, but now with an extra 300 watts on the roof, for 465 watts total, I don't think we're going to need the charger portion.

Enjoy,

Perry
