Off-Grid Solar with Lithium Battery Bank
Challenge:
Needed to remove an outdated 800W wet lead acid battery-based solar system at an off-grid lakehouse and replace it with a new state of the art 5.2 KW system and Lithium powered battery bank. The Finished solar system powers the whole home, all indoor and outdoor lighting, septic pump, well pump, TVs and kitchen appliances including microwave.
Solution:
- EXISTING ELECTRICAL CONVERSION
Removed old solar connections but kept various connections to household devices intact while adding new system cabling and equipment - SOLAR PANELS
Installed 16 solar panels on rooftop providing 5.2KW of power - AUTOMATIC GENERATOR STARTUP
Included an Automatic Generator Start (AGS) to seamlessly support solar power when batteries get low - LITHIUM IRON PHOSPHATE BATTERY CABINET
Installed a 48V 14.4KWH battery cabinet - RAPID SHUTDOWN
System design includes rapid shutdown disconnects with RSD switch for safety, as per the new CEC standards - CONTROLLER
Installed a 600V controller that grabs the DC power from the solar arrays and converts it to 48V DC, supplying energy to the battery bank and the inverter charger - INVERTER CHARGER
Installed an Inverter Charger to convert DC to AC power and charge batteries via a generator when sun power is low.
Results:
Customer is now able to power his home without the daily use of a generator which previously had to run for 3 to 5 hours every day. With a top of the line battery monitor, he now has access to detailed and accurate information on his battery bank. The battery monitor indicates hours of battery run time and determines the state of charge (SOC). He now can see on the display, the amount of energy (amp hours) coming in and the amount of energy (in amp hours) leaving through usage. Monitoring, especially with a lithium battery bank, is very important.
