cool318: From dusk till dawn is about 12hours of light, but varies with daylight savings and soltice. You can use 1 watts or 3 watts high power LEDs in parallel combination of whatever number of chips you intend to use. You can use LED drivers (specific for the number of LED chips series-parallel arrangement) or you can construct simple current limiting resistor circuits as drivers. The 1 watt chips usually have a running current of 350mA, 3 watts chips 700mA while both operate on voltage range of between 3.2v to 3.5v. You may or may not incorporate LED lenses or beam diffusers to widen the beam angle of your lights. Your choice of power storage could be smf battery (heavier, cheaper) or lithium chemistry based batteries (cleaner, light weight but costlier). You will need CC specific for the battery types you intend to use. Some CC come with dusk till dawn option where they sense the solar power voltage to determine when to output power to the load (lights). In such case, you may not require photocell. I have tried this before and I wasn't totally satisfied with the set up (due to the limited time I have for leisure from work) so I just went with the simpler options. For the solar stand alone street lights, I purchased some solar light system from konga and just hardwired a LDR for the dusk-dawn cycle. There is one called "saroda" with 6v 3.5watt panel and 6volt output to two 1 watt bulbs claimed to run for 10 hrs on both bulbs after full charge. The batteries are 2200mah Li-ion in 2s 2p configuration. I modded the power consumption of the lights using limiting resistors to further extend the working time to around 16 hours but with some hardly noticeable reduction in intensity of the lights. The panels are placed on top of each pole. For the wall security lights, I opted for 12volt DC set up. Got 12-24volt AC/DC powered lights (the 1 watts type consumes around 0.10A at 12volts producing around 100 lumen). It's made with 5050smd LEDs and is bipolarity, meaning it works in any direction you have the polarity. About 10 of such connected in parallel configuration. Dusk-dawn cycle is via LDR. All powered by a portable 12volt 12ah solar system(20 watt poly solar included) which I got off of konga. I recently changed the source to a Li-ion powered set up. |

Oga Pranil, many thanks to your recommendations, I finally pulled the trigger and swapped out my 1hp bedroom AC for a 1hp LG Inverter AC and boy did I make power savings? My net AH removed overnight using the inverter AC in Gen Mode has dropped from 230Ah to about 150Ah - at a reference average voltage of about 50v this is a ~4kwh daily savings. With the old AC I would reduce target temperature to about 24°C to 25°C and sometimes even use a timer to manage power consumption - with the inverter AC, I set a 16°C target and activate Gen Mode and I'm good to go - if I wake up middle of the night, it is cold enough that I have to set the room temperature warmer so that I and the Madam do not freeze to death ![]() The inverter AC cools a bit different than the traditional AC - one may not get that frosty chill but it is more than cool/cold enough to sleep very comfortably in. If this performance keeps up, this would be the best purchase decision I made in the month of April 2018. pranil: 7 Likes |

DBlackCeazer: holy moly,24 units 2v 1000ah, wow that must have cost a fortune..whats the cot per unit? what is the charging current of the must power?...the 6kva is 40 amps, this i inadequate to charge properly a 48v 1000ah bank, following the C/10 rule, you may get away with this if you dont depelete the bank below 605 dod, or you have solar charging input, as the bank needs to see >100 amp charging current periodically, to avoid sulphation. such battery banks are best fitted with the german/usa inverters, that output >120amps charging current easily...eg the 4kw magnum or schenider is capable of this easily 2 Likes |

Any of the many MustPower brands are decent performers and generally okay brands - they are good for heavy duty loads but are also notorious battery power guzzlers. You want to be sure you really need a 6kw/7.5kva inverter before you buy one as you are looking at a 230watts per hour no load/idle power draw. Again you have a pretty huge battery bank so inverter self consumption should not be too much of an issue. As for the DC power supplies or rectifiers as you call them, I would suggest you first install your inverter and see if it has sufficient charging amps (I have measured 50a on some models) to fill up your battery bank within the time frame you desire. Those DC power supplies are rated for like max 53.5volts (unadjusted) and the likelihood is that they would charge for no more than one hour before your inverter has taken the battery terminal voltage above 53.5volts to the point where they shut off - they would only give you any real mileage if you deep discharge your batteries and even then, they tend to reduce charging amps and quickly stop charging altogether when they sense a higher voltage source (your inverter) Lastly, these MustPower inverters are typically sold as is with not very organised service center or repair help available - should you run into issues, you will be at the mercy of your supplier for a fix or you try your luck with any repairer you can find. All in all a decent performer and good value for money sha. DBlackCeazer: 2 Likes |

NiyiOmoIyunade: Congrats - You will Enjoy it. One suggestion though - Run the AC in 25 /26 DEG setpoint in normal mode till you go to sleep and then put on GEN mode. setting the target temp lower actually makes the AC work harder drawing excess power and in case of thermals the heat loss/transfer is directly proportional to the temp difference between two objects - https://en.wikipedia.org/wiki/Heat_transfer_coefficient By telling the AC the desired temperature as 18 you are actually running at the same rate possible when setting at 26 but with the 18 DEG reaching the required temperature the compressor keeps on working hard to reach the 18 DEG. In conventional AC's the compressor was cycled between ON and off based on time and some intelligent logic thus setting 18 made the compressor run more of the time so everybody got into the habit of setting it lower to cool faster with InverterAC"s the compressor changes the speed and thus heat transfer ( cooling power) based on the actual temp at the inlet and the set temperature. Once reaching the desired temp it slows down the speed reducing the power consumption. The GEN mode restricts the faster speed even if the temp difference is Large ( thus allowing the power saving) or in case of smaller inverters /generators the peak load. The biggest savings come from the variable speed of the compressor with the additional advantage of not having the inverter deal with surge starting of the compressor motor every few minutes and operating at a better power factor than an inductive motor IN my case I am using 4 AC's with 20 KWH batteries so If I have to deal with an overnight power cut I run the AC's in turbo mode with GEN ON for 1 hour and then change them to power save for the night. It remains pleasant enough and I get a better sleep knowing I dont have to get up in the middle of the night because of inverter beeping due to low battery ![]() In the Long run it will also help sealing the windows with foam and in addition I use this product funder the door to prevent the heat loss https://www.amazon.com/Excluder-Self-adhesive-Stripping-Soundproofing-Insulation/ and an intelligent controller to manage the temp settings dynamically ambiclimate -https://www.amazon.com/Ambi-Climate-AI-powered-conditioner-controller/dp/B076BCPJP4 I have managed a clever but simple trick The ambiclimate is set to Power teh AC at 6 PM but the power to ambiclimate comes from non inverter socket so AMBI swicthes on the AC at 6 PM only if NEPA is present otherwise it is off . While sleeping I change it to Inverter socket so It keeps the temp constant e.g. if it is already below 24 DEG OUTSIDE it will swicth offf the AC mode. 3 Likes |

earthrealm:thanks for the response, those batteries were used at home where we ve a prag 10kva inverter and 2kva solar system installed. We recently received 16 pcs of 6v rolls flooded batteries from the us. So we are looking at moving the 2v battery to our office, hence the need for a new inverter, not looking at spending more than 350k on that. Spoke to a supplier here in Nigeria who suggested the setup I mentioned earlier. |

These are very lovely dashboard indicators my Oga Dapsyra. When I look at your power generated 23kwh vs. consumed 3kwh - does this mean you flogged your 21kwh battery bank about 18kwh overnight? This is like 85% DoD. Though you are using the much vaunted LTO batteries - I am curious to know what kind of overnight loads are consuming 18kwh? Lastly what monitoring app is giving you such colorful and vibrant dashboards? dapsyra: 1 Like |
