Generally, the inspectors cannot inspect to a code that has not been adopted by "their agency"... I don't know how it works in your area--But in my area inspectors are not liable for t…1 · -
Re: What is the power factor of a pv system and the factors affecting it ?
Are you asking about Grid Tied Inverter type systems? If so... The first thing to uinderstand is that AC powered systems only have unity power factor (PF = 1.0) if the loads are purely resistive (hea…1 · -
Re: Inverter Neutral tie
Ground rods--They really only are useful for lightning and static discharge control. It does not really do much for day to day 120/240 VAC 60 Hz system operation (~25 Ohms maximum from ground rod to …1 · -
Re: Inverter Neutral tie
The typical PSW/TSW (pure/true sinewave) inverter has an isolated AC output... Basically a transformer between the DC battery bus and the AC output (hot/neutral/etc.) Typical MSW (modified sine/squar…1 · -
Re: Just got a great deal on a little system
Yes. Virginia. Very roughly, I would suggest a maximum of 1,200 to 2 000 Watts for the inverter maximum with 12 volt battery bank. 1,200 Watts at 12 volt is over 100 amps of current. Requires very he…1 ·
