When an inductive motor, such as an air conditioner, starts it creates a large current surge. High frequency inverters such as the one shown above are fine for small inductive loads but when trying to power large electric motors, low frequency inverters such as Aims, Victron, and Magnum are more suitable. You can usually tell because a low frequency inverter will be about 3 times as heavy due to the iron core transformer and most likely 3 times as expensive. https://images.squarespace-cdn.com/content/v1/5dd0ac39fcb3826c703bba89/a9fefc64-85c2-4515-a860-93decee1dc25/IMG_20211113_165159.jpg Projects - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://www.highdesertoffgrid.com/grounding daily 0.75 2020-08-09 https://images.squarespace-cdn.com/content/v1/5dd0ac39fcb3826c703bba89/1596637465790-NO4M739WU33XYJGO93D7/FuseboxWithGrounds.JPG Grounding https://www.highdesertoffgrid.com/2448-home-install daily 0.75 2020-12-25 https://images.squarespace-cdn.com/content/v1/5dd0ac39fcb3826c703bba89/1608928730987-DYMMY4YXMWUYZ8WYFRWY/24%2C48v+lithium+home.png 24/48 home install The above solar configuration is just an example. Please go to Solar Configuration to see more info on possible solar layouts. https://www.highdesertoffgrid.com/pv-configuration daily 0.75 2020-12-25 https://images.squarespace-cdn.com/content/v1/5dd0ac39fcb3826c703bba89/1608926398072-7AI1QN4C8A5D36RG2CPM/4S1P.png PV Configuration 4S1P is quite the opposite of a 1S4P. We now stack all the voltages so for the same 100 watt 12v panels we would be producing 1/4 the amperage at 4 times the voltage. This array would produce about 5.5 amps at 72 volts. When sizing a charge controller it important to use Voc which is the voltage at open circuit. The Voc of a 12v panel can be found on the back of your panel but is usually about 22v. A 4S array of these panels would be about 88 volts making this configuration no good for a 75/15 charge controller. We could switch the configuration of panels or move up to a larger controller. https://images.squarespace-cdn.com/content/v1/5dd0ac39fcb3826c703bba89/1608822020352-HHGIWRD15HD207RMOE3Q/1S4P.png PV Configuration 1S4P means 1 set of panels in series, 4 panels in parallel, hence 1 series 4 parallel. If the above array were 100 watt, 12 volt panels (18Vmp), they would produce about 22 amps at maximum. A 75/15 charge controller would only be able to deliver 15 amps at battery voltage which has to be 5 volts below panel voltage. So most likely this array would not be most suitable for a 75/15. https://images.squarespace-cdn.com/content/v1/5dd0ac39fcb3826c703bba89/1608822394926-1JTTQSMYXRKJ4GNONW20/victron-smart-solar-75-15-1.png PV Configuration Before we start talking about PV configuration we need a clear understanding of the charge controller. If you are dealing with a PWM charge controller then you need to try and match panel voltage with battery voltage. If we are using a MPPT charger as shown above we can use much higher panel voltage by stacking them in series. We need to understand the two number for example this controller (75/15). This charger can accept maximum 75 volts at Voc (panel open circuit voltage which can be found on back of panel). The 15 denotes the maximum amperage the charge controller will deliver in this case 15 amps. If our battery voltage is 12v the maximum power this will deliver is 180- watts, if we use a 24v battery it will deliver 360 watts. https://images.squarespace-cdn.com/content/v1/5dd0ac39fcb3826c703bba89/1608925712464-NE3N84XGHEDCTO8NAGHY/2S2P.png PV Configuration 2S2P is a combination of the two above. With the same panels we will now produce about 11 amps at 36volts (44Voc). With a 12v battery we would be able to only harness 15 amps or 180 watts which would be only half of the potential of this array. With a 24v battery we could harness 360 watts of solar (90%) This would be those most ideal configuration if our only controller option was 75/15 although ti would be reccomended to move to the next size up to harness all the solar potential. https://www.highdesertoffgrid.com/lithium-diagrams-24v daily 0.75 2020-12-25 https://images.squarespace-cdn.com/content/v1/5dd0ac39fcb3826c703bba89/1608932693571-CI5MH6YGRTLOQCCQLK5Y/24V+Schematic+Lithium.png 24v/48v https://www.highdesertoffgrid.com/automated-smart-off-grid-1 daily 0.75 2024-07-08 https://images.squarespace-cdn.com/content/v1/5dd0ac39fcb3826c703bba89/24956bb6-4dbc-4853-9cea-be6fd6e763f8/KIMG1928.jpg EV Charging - Make it stand out Whatever it is, the way you tell your story online can make all the difference.
