    New high efficiency solar concept no battery

    Introduction: Hi all, I am not a company or business of any kind but a retired tech that is trying to win at this new green power transition, this project deals with mains voltages (126) VAC! (181) VDC! will require correct wire sizes,fusing, insulation and isolation transformers to interact with other solar or grid power systems.Do not attempt anything you read or see in this thread unless you are comfortable working with high voltages!
    After 7 years years of solar power in my home Gopower IC3000 the 4 deep cycle batteries started to degrade and needed replacement, after spending one arm and a leg in replacement cost it dawned on me everything I had saved over the past 7 years just went into new batteries!
    This project from the ground up is a no battery,no charge controller, no maintainance and fully automatic normal day (2 second grid/green transfer at 9AM) (2 second green/grid transfer around 6PM). This new starter 800watt system powers the lights,fans,bug zapper, security cams and mini fridge daily in my home.

    Before going any further I would like the Moderators input on this subject, tired of posting this important information in the morning and ending up on page 50 of other solar forms in the afternoon.
    These post start with interactions and get push all the way down.

    Similar in efficiency to solar micro inverters at each solar PV panel but much more easy and cost effective, also should I upload the photos and videos here or link to another solar forum?

    Hello GridWorks Green and welcome to Solar Panel Talk

    I am sure someone will be able to answer your questions. I would try to post the pictures here because linking another website may send the post to moderation which will delay someone other then the Mods from seeing it due to our spam software.

      Thank you SunEagle.
      Unfortunately I have run into error in uploading photos and must leave for the rest of the afternoon to do plumbing repairs, I have no issues with post a copy of everything here. Follow this link for now to see details:

        Yes batteries are a big problem. Some like me avoid batteries using a
        Power Company Net Metering contract. To me the PoCo is a 100%
        efficient, infinite capacity, zero maintenance and cost battery. Bruce Roe

          Bruce, you have a good deal, but you do realize that if your POCO gave the same deal to every one of their customers and they took them up on it......the POCO would be bankrupt in a heartbeat.

            I disagree. A POCO will just go crying to the PUC and request a rate increase to keep their customers.

              I use solar power much like most people would use a gas generator and a transfer switch, have never given much thought to selling it back to the power co.
              Here to answer any questions, sun sensor has improved every day calling it 99% good for matching the power curve when transfer of power is needed.
              Still can't upload pictures or videos, gives error message,help please

              Before years end hope to solve car charging on the new power system and make the switcher units seamless or a fraction of the two seconds they are currently.

                Some of yesterdays events:
                Solid overcast day but the lights stayed on nice and bright from 10AM to 5PM on direct drive solar, sun sensor is now working perfectly.

                Just 9 standard Windy Nation 100 watt panels, a replacement pure sine power board and isolation transformer to drive the house lights circuit.

                Add a sun sensor and switcher unit for fully automatic swap to grid or second power source, A simple double pole double throw 15 amp switch can let you test drive the whole experience.

                Solar-off-grid switch, always stop for a second at the off position, secret to the whole switches thing.

                  FYI bonus post : Here is a list of things you should not connect to your green power inverter systems, going to also suggest alternatives for each.

                  #1 Standard Vacuum cleaner/use LI-ION rechargeable instead.

                  #2 Table saw and circular saws/use rechargeable alternatives.

                  #3 Full size cooking appliances/It is not so much the load but thermostats and timers going on and off that seems to smoke the FETs, need a strong inverter to even consider cooking on green energy. Small cookers like a crockpot can prepare a hot meal.
                  Best to use gas for cooking.

                  #4 Surge suppressor power strips normally have a second red led light on them/ Avoid them like the plague on green power systems and switcher systems. (Pure havoc and blown fuses) see picture.

                  #5 Starting motors/ although dangerous capacitors can assist in motor starting and large battery systems, on A/C and fridge compressors a normal 5-7 minutes delay is needed to balance the freon system and have an easy restart (normal 5 min on A/C units and small refrigerator about 7 mins) nothing much harder on an inverter than a stalled compressor motor.

                  #6 I would not recommend things that heats water like a dish washer or large motors or connect an arc welder unless you use special cycles or over sized industrial power inverters and such.

                  I recommend getting a strong good quality inverter or power board, cheap inverters rarely last a year.

                  For a solar newbie or off grid user this list could save you big time,I smoked many expensive inverters over the items mentioned above

                    Not directly related to the new power system but an observation on the older system I run, recently upgraded to an Epever 100 amp charger charge controller it operates on 12 panels in two parallel strings of 6 because I run a 12 Volt battery system the owners manual states I won't get the full the full 100 amps, during EV car charging the controller maxes out at 71 amps any other time the max is 35-40 amps, used one of the power boards hooked into the Epever PV input except for noise created by the Mppt circuit all that excess power on a sunny day is just wasted, Talking 100s of watts of slack in the systems.

                      Actually they were already mad at me in the previous century, because
                      I was under 10KWh a day except when I needed to run the gas furnace.
                      Under 5000KWh a year. Lots of bills under $20, but they could not
                      openly criticize someone who was being very energy efficient.

                      Today is not much different, still buying very little from them, but now
                      they have another excuse to be upset. All this copper installed and
                      my own transformer for this originally all electric home. But I am
                      helping them level their load by running all the air conditioners down
                      the street when its really hot.

                      But not everyone could ever do this, because there would be too
                      much energy in summer and not enough in winter. Saturate the
                      adjustment limits of the grid. So for now I contribute to green energy,
                      but solar cannot exclusively solve those problems.

                      Who I am really giving it to is the gas company, who was giving it to
                      me at an increasing rate the previous century. Today they get nothing
                      from me, am immune to todays home problems. Bruce Roe

                        My overall take, being off grid is an expensive and limiting thing.
                        Those that do are doing a lot of work to set up burning
                        firewood and fossil fuels. Bruce Roe

                          Like to help some in Florida reclaim their house, off grid living sounds romantic but a newbie can suffer big time especially in winter climate.
                          Asked to help with making dual mini splits work off grid, guy was shattered to find out he could not even run one overnight.

                            Not if they change their pricing model to account for that.

                              Sounds like you found out how much "low cost" lead acid batteries cost you.

                              I'd recommend looking at a small LFP system (1-3kwhr) to allow you to do things like start motor loads, do PWM control on EV charging if you want to do that, and work more efficiently on partly cloudy days. You can do straight solar, but you end up with a much larger system than you need to support things like compressor start.
