This solar guy’s price is good especially if that includes installation… I hope it includes charge controllers and supplimental small battery charger that allows to use PHCN and Generator to charge batteries for days when sun is not shining much.. With all of that and no more than 500k naira, its a good price..

Its true, battery inverter alone will not be saving money because gas for generator and PHCN bill will stay the same or increase, but there will be some backup power to claim for the cost… Most people dont have expensive throttle control generators that auto-reduce the throttle when useage is below the generators watt capacity.. That means most people always have a surplus of electricity just wasting when they run the generator.. Storing that surplus on a battery-inverter system is not a watse of energy ,but a capture and savings of energy… The same cannot be said about PHCN.. PHCN is all around a waste of money right to the point of billing for a non existent product called electricity..

All these together are enough to hold over a complete power supply.. Wind generator/turbine is another great supplimental to add as they produce more current when active than a solar panel… With wind added as supplimental ,it will save generator cost.. Days when it rains all day with sun clouded out with dark clouds, you will have the wind blowing… Wind generator will be there to supplement very well…

I have a Honda EU generator, very quiet and with eco throttle.. The eco throttle is an automatic throttle which reduces petrol consumption based on the electric load being drawn.. But it cannot reduce the throttle to adjust to less than 25% of capacity even if you only use 10% capacity… But it is still good and saves money ,because cheaper basic generators burn petrol at full throttle at all times under any load below capacity…

Honda eu generators sell for $2600 for 3kW peak and $1200 for 2kW peak.. The 3kv peak one can take up to 20 hours to burn 3.4 gallons of petrol for constant supply at 400watts which is enough for 2 tV’s and 10 efficient lights… It will be plenty to charge batteries as well.

The high price is only a starting point issue.. People who buy the cheap generators will replace them or repair them far more often than these honda generators.. By the time i spend $2700 over 5 years of replacing and maintaining cheap generators, the Honda eu generator will still be running fine & ready for another 5 years after some major service for the price of one new cheap generator… And thats after the generator was working 8 hours a day for 5 years and being maintained well..

Solar is not cheap either.. It works best for those who invest a large starter cost that makes a $2700 generator seem like a small accessory.. Full home service power plant balanced with wind, solar and battery charger to plug into alternative fuel generator ,will be a complete self contained system that can call PHCN to come collect their rubbish meter,wires and poles… 1million Naira should be enough unless you live in a palace or use industrial grade machines.

The guy’s price is good.. I lived with solar and genrator for ten years and did my own installation and maintainance.. I have learned first hand and am also putting together another small solar kit as we speak.. I have ordered the accessories and will get the solar panels and batteries later locally when i am ready to instal.. My inverter, charge controller and accessories will all fit inside a small back pack and carry go anywhere there are batteries and solar panels..

See the picture below of what i have right now waiting to do a set up of a 1kw peak output system… The inverter is not in the picture, i have that being shipped direct to the site and i will carry these components here with me in my back pack with room to spare for some personal things.

Remember, peak output is what a system is rated for.. If you want to actually sustain 3kv, then buy a 4 or 5 kvwSystem.. 3 kw system is good for 2.5kw.. My 1 kw system is only good to sustain .8kw load… Advertised rating is only for peak use which can only be sustained for short periods of time.. Some will advertise extreme peaks almost double the basic rating.. But if they dont advertise a separate peak rating, then use it only to 75% or less of the Watt rating.. It makes a difference in how long the inverter will last.. Heavy duty expensive inverters usually last many years, but the cheaper smaller ones dont last more than a year under daily use under 75% load for most of the day.. Some cheap ones wont even last a few months without a separate load controller to sheild them from the battery bank’s high amperage capacity… The charge comtroller i have here, controls load, charge and input.. They have 360 watt or 30amp rating for DC load…

Some solar panels are huge and put out over 200 watts while others are small and put out 50 watts or less.. Count the watts on everything being given to you and also account for amps… The batteries should be rated in amps… 150 watt battery has no power for the claims above.. If it is 150 amps to the battery, then we have power.. 200 amps battery at 12 volts will be 200×12= 2400watts… 2400 watts of 12 volt DC must then covert to 24 volts and then or directly to 220 volts.. By the time the inverter changes 12volt dc to 220 volts ac, the watts available per hour, will be divided by 20 and then adjusted for the gaps in current alternatiings .. 120 ac watts per hour maximum per 12 volt battery.. If they are four, then 4 hours at that rate…

Some batteries are 100amp and others 220amps… Some are 6 volt batteries while others are 12 volt… 6 volt is easier to charge with smaller charges.. 12 volt will take longer to charge with small loads, unless it is a lower amp battery like 100amp or less 12volt battery.. Also no battery is designed to give out its full amp load.. So even after all these calculations and rated amps, the actual load available to draw, will be less and over less hours… The good thing is that solar panels will add to the batteries output as we draw load from the batteries.. But this is only during the day when there is sun.. So day time use will be far more yeilding than night time use… This is why the best systems are balanced with wind and supplemental battery chargers…

DC watts and DC amps are not equal to AC watts and AC amps… There is a lot changed in the inversion and conversions done by inverters and converters..Also power is lost from heat and noise in the components such as inverter and charge controllers…

You can pay a lot of money for very little electricity with solar, and even be misled if you dont understand the workings and conversions of voltage, watts and amps… Also to know the safe operating parameters of each of the system’s components…
