– Though there are many ratings/specifications to consider, the basic primary rating of an inverter is power. Because it would require knowing your entire installation, expectations, and demands thereof. – “So what should we be looking for?” I cannot answer that. – Yes, if you add more appliances you will need a more powerful inverter to cope with the extra consumption. However with that said, here are a few notations… It will require research and understanding of electricity/electronics, and the overall subject in general (beyond the scope of this article and my comment) to get into in-depth design choices. Inverters range in price from less than $100 to many thousands of dollars. Won’t be a bad thing unless other people keep winning the Ken Dalton, Then, if $$$ and time allow, re-wire system to 48VDC and have 24VDC backup system. Next step is to get back up to 24 VDC on PVs and associated equipment.
#SOLAR POWER SYSTEM DIAGRAM GENERATOR#
Generator only has 12 VDC output for charging lead-acid batteries v. Even an ‘all batteries low’, start the generator box.īiggest drawback was I had battery problems and had to re-wire everything to 12 VDC. I do have a few homemade automated steps in the system. I have lockouts hanging on the wall next to the load center to prevent ‘accidental’ re-connection. Like Ken, my switchover of the mains is manual. Might even put in a 220VAC GFI, just in case. Since you have two systems, I would look at dedicating one to the water pump, acquire a 220VAC inverter, and manually control the water pump. There’s a lot of places that have good deals on ‘last years’ products. Keep track of the prices, and jump on the best deal when it pops up. Your better effort, IMHO, is to search a lot. > Renogy Kit – 200 Watt, 12-Volt, 40-Amp, MPPT Controller A few panels up on the roof can make boondocking a bit more comfortable! Solar power systems are also becoming popular for RV’s. Maybe just several hundred watts to charge several deep cell 12-volt batteries connected to an inverter (for example). Some people may choose to put together (or at least have on hand) a small system for ‘just in case’. I’ve integrated it through ‘transfer switches’ for some of my home’s electrical circuit breakers. I built an off-grid solar power system which is ‘side-by-side’ with my home’s grid power. Hover, It’s Worthwhile for Many!ĭespite the cost of a given solar power system, for many it’s a worthwhile investment.Įxample: If purchasing a new property with land far from the nearest road with electric utilities, it may actually (very likely) cost less to implement a solar power system than pay to run electricity to your property.įor the preparedness minded, simply having a very basic solar power system (or bigger) provides some peace of mind (at least it did for me). Why? Because a cost analysis of a solar power system compared with that of your electric utility bill will speak for itself.ĭepending on the system design and usage, the break even point varies widely. It may take years to reach a break-even point. One could argue that from strictly a cost savings point of view it might not be practical.
Though the costs of solar are coming down! It depends on your objectives! First, lets face it… To implement solar energy is not cheap compared to today’s energy from the grid.
