Connecting PSW inverter directly to service panel


Note that the simplest solution may be net metering.Where permitted, this uses inverters that monitor and synch with the power lines, and therefore can be connected in parallel with the grid. At the same time, your meter is replaced with one that can count both forward and backward; if you are producing more power than you need the excess gets sold to the grid, and when the balance goes the other way (eg at night), or when clouds cut your production) you buy power.

Major advantages include continuous aitomatic balancing of the two sources, no need to maintain a battery bank, and the joy of the midsummer bill when the power company may owe you money. (I haven't quite gotten a negative bill yet -- I've gotten negative grid usage, but not enough to overcome the $6/month account fee.)

Disadvantage is that, for safety reasons, these systems are designed to shut down when power is lost on the grid to avoid the risk of electrocuting someone who would have expected the...

yes. But, you will require a special type of inverter that performs both MPPT operation and Inverter operation.

These are common in market these days as a lot of homes are powered with solar.

This typically sends power to grid through special smart metre which can send power as well as receive power from grid. You will not be powering your house with solar instead you will be receiving power from grid as usual. But what you pay changes.

Smart meter calculates net amount you need to pay to govt. i.e, Total cost of generation - Total cost of your consumption.

You may also power your house with Solar power without using grid utility but it will not be economic and advisable as cost of maintenance, Battery storage etc will be high, and its life time is also less.

Mostly cost for excess generation will be compensated in your next...

Re: connecting inverter with bonded neutral to panel with same ?

If you wire the Green wire ground and the White Neutral directly to your home's main panel--You will usually see that the Green Wire bus bar and the White neutral bus bar are exactly the same bus bar, or the two are directly connected together electrically via a jumper wire or grounding screw. So, connecting the two Green and White wires to the same bus is OK... Personally, I would keep the two G&W wire the same AWG size... Since they are in parallel, you will have operating AC current flowing through both of them and there is no way to know (ahead of time) if they are going the "split" the current flow in 1/2 or if one or the other wire will be carrying 100% of the AC neutral current (since both wires are connected in parallel with unknown common connections at both ends).

The Transfer Switch Step #3 (black wire to 50 amp breaker in panel)... While technically, you can connect the...

Installing a Small Inverter in a Motor Home

An inverter is really an essential item in your motor home, as it converts 12 volts DC from your battery or solar cell into household style 230 volts alternating current. This makes your motor home even more like "home". Rather oddly very few models come with one fitted as standard. Sunliner is a notable exception and of course most of the $180,000.00 plus models from Winnebago and Swagman. If you know nothing about inverters this article is for you, as even if you have no intention of installing one yourself it will make you more conversant with what you need to buy or have fitted! As usual this is another minefield area, and yes it easy to make expensive mistakes and worse buy an unsafe unit. We have made mistakes along the way and these are detailed here. Generators and inverters both perform the same task. The difference is that an inverter only uses full power when the...
