pranil: Nice going! I'd been dreaming of such panels. Didn't know they actually exist already. Let's hope they make their way into our market soon. The numbers seem fantastic though |

Saipro:I have a Victron Bidirectional Quattro( multi) so I am planning to try using a small Grid tie Inverter with solar panels and a current sensor - See atttached PDF - The sensor can be similar to this -https://www.ev-power.eu/Measure-Test-Tools-1-1/Current-Monitoring-Relay-PRI-52-AC-0-5A-25A-CE.html#tab2 A soladin or APS grid inverter will be ideal choice ( 1 KW to 2 KW) - http://www.mastervolt.com/products/solar-inverters/soladin-1000-web/ APS- http://www.apsmicroinverter.nl/ The idea is that whenever the current sensor senses the Current flowing from PV panels to Multi or from Multi to PV panels the sensor after 1 min will switch off the Powercontactor feeding the water heater/Boiler - The contractor timer waits for 10-20 min and resets if there is no current flow then the water heater remains connected till the current sensor switches it off the idea being that in daytime the solar PV inverter will directly feed power to water heater. After midday when the heater gets thermal cutoff there is no power draw from heater the excess energy is fed back through multi to loads and battery You can set timers( time of Day) and even a bypass switch to feed the heater directly from Multi in winter or night if some top up heat is required. Alternatively, a time of the day timer can be fitted to disconnect heater in the evenings /night to prevent draw from batteries ( in case your inverter is not passing the grid to the heater) Since the grid tie inverters have efficiencies between 95-97 % you are using the full yield and compared to the DC heating element you can locate your panels anywhere and heater anywhere in the house as long as they are connected at AC side Also, the solar panels can be smaller say 500 watts ( set current control higher than the difference of Panel average yield and heating load) OR They can be much larger ( set current control or a lower value say 1 to 2 amps) In my case I am planning to use a similar setup but instead of heater use it for running an air conditioner - The one advantage I have is that the AC is inverter type. so it ramps up the load from 100 Watt to 900 watts in linear fashion giving ample time to the contractor to act and disconnect if it is a cloudy day without much tick toc effect

babaegun: I have 300w AC Areo dry Iron I have been using since 2009 when I have not dreamt of inverter or solar. it so efficient that it melted the lower plastic casing and it's thermostat knob making me to hate using it for sometime. Last year, with the fear of recession and the need to protect my battery bank, I had to dig it out from my dusty store & insulate the casing from it's element or iron base. now I enjoy pressing cloths anytime of d day with just 300w on my 2kva/1600w inverter. I have since dumped my Siemens 2200w water iron. for those looking for inverter friendly pressing iron, check it out maybe you will find an improved version of it. 1 Like

pranil: Oga Pranil, after all your previous rantings about the supposed "Ilegality" of using grid-tie inverters in an off-grid system, you are now dreaming of implementing an AC-coupled system using the same grid-tie inverter (in this case microinverters hard-coupled to PV panels)? You are trying to implement a variation of an off-grid, AC-Coupled system with grid-tie inverters called a "GRID-FREE" system, yet you argue that grid-tie inverters must inject into the national grid. Please explain to the forum how you plan to stabilize the national grid and also show us all the NEC / NERC code compliance certificates and permits that must be issued to you by our beloved 1 Like |

jazzman2: I thought we let this go a while back. The hazards of a self-contained micro-grid cannot be over-emphasized but is beautiful when properly setup. If you follow SMA installations, you'd discover it's the preferred mode of using Sunny Boys in an off-grid setup (backed by a Sunny Island master). Chris on this forum seems to have installed quite a few units and I vividly remember seeing pictures of a Sunny Boy/Sunny Island combo setup by his company on this forum. He could lend us his practical experience rather than us drawing abstractions. |

jazzman2: ![]() I only pointed out the dangers both technical and legal and left the choice to consumers in the absence of any regulation on GRID Tie since the community is full of D.I>Y enthusiast who might lack the knowledge to make a suitable decision . May be it was misunderstood F.y.i. in my case is I am using a islanding relay and a Em24 Energy meter to ensure that the grid export is prevented along with PV assitant and a Venus GX If you want I can send you my discussion with Victron ,EVpower and ,d Soladin on applying Microinverter. Even Victron has not done it before and I am trying to test a solution Infact both Soladin and victron advised me against it as it has never been done before making me more curious to try it out |

DUNKA: dunka, plumbing does not need to be a headache for you when it comes to solar water heating. first of all, get the package and measure the total height of the assembly, i.e from the top of the water heater tank to the foot of the frame carrying it. add one or two feet to this value. that would be the clearance from the bottom of the main water tank to the top of the water heater tank. after installing the water heater, run your hot water lines direct from the hot water outlet to the inlet of your existing electric water heater inlet. use a t-connection copper tube. you only need to bore a little hole from outside your bathroom to gain access to the existing plumbing.use the t-connection to introduce the hot water into your bathroom. |

Re: Solar Energy, A Complement To FTA by earthrealm(m): 4:47am On Jul 21, 2017 |
GeorgeD1: just wondering...so for an old house....one would have to run the hot water pipe from the solar heater to the various hot water points in the house?...........if yes..that would be untidy and a bit difficult in some builds. for a new house having a central hot water piping traverse the whole house might be a tidier option...though when one factors in the cost of the copper pipes...it might add up to much...especially for a large build eg 5br duplex.. what are your thoughts/advice? |
Re: Solar Energy, A Complement To FTA by GeorgeD1(m): 10:15am On Jul 21, 2017 |
DUNKA: dunka, i dismantled them and gave them away. there was really no point in keeping them around as i wouldn't be needing them anymore. and, several months down the line, i'm still glad i took that step. |
Re: Solar Energy, A Complement To FTA by GeorgeD1(m): 12:04pm On Jul 21, 2017 |
earthrealm: earthrealm, yes, for a house with an already existing electric hot water plumbing network, you definitely have to run your solar water heater hot line to the various points but its not really as untidy as you think. provided it has an existing hot water line, you can retrofit the solar water heater outlet to link up with your existing plumbing system. for a new house, it becomes even better. the cost of copper plumbing drops drastically because in this instance you can run your hot water line directly either from the roof downwards or through the floor of the house. |
Re: Solar Energy, A Complement To FTA by pranil(m): 3:06pm On Jul 21, 2017 |
GeorgeD1: Problem is that my cold water is boosted at 3 Bar which means I have to boost Hot water also with a booster to match user expectation on temperature versus mixer handle position. Also, Hot water boosters /recirculation pumps are on the pricier side How much outlet temperature normally you get on a sunny day and cloudy day. I might use the hot water as preheated water for one boiler /heater used for the main bathroom and later think of adding other rooms Where did you get your system from? Any issues with the pumps controllers ? |
