Sol-Ark Inverters
Sol-Ark Inverters
The Sol-Ark inverters can be used as a grid-tie PV inverter with or without a battery, or as an off grid inverter. The inverters feature Grid-Sell without batteries; Grid-Sell with battery backup; Grid-tied with Zero Export with or without storage; Time-of-Use/Peak Shaving; prioritized charging from renewables; and off grid. The Zero Export features can use any of the loads in the house, including those on the main service panel, what we call primary self-supply. Backup power is available to support the loads connected to the backup loads panel, with an extremely fast transfer time of 4ms.
These inverters use DC coupling from solar to grid and battery for greater overall efficiency. An AC coupled direct grid-tie inverter can also be used as the only source of solar or combined with DC coupled solar. The Sol-Ark can use any commonly available 48 VDC battery bank, including flooded, AGM, gel lead acid batteries, or 48 VDC nominal Lithium batteries. PV input voltage range is 150-500 VDC, allowing for longer PV strings. There are two (three for the Sol-Ark 15k) MPPT inputs so that most any combination of modules can be accommodated. The inverter has both ground fault and arc fault protection built in. CT's can be installed on the house AC lines for export control and monitoring.A battery temperature sensor, ground fault, and arc fault protection are included. There is a color touch screen on the front of the inverter (keep out of the sun). They are capable of WiFi and Ethernet to app or internet for monitoring and control.
For the Sol-Ark 5k, Sol-Ark 8k and Sol-Ark 12k the standby draw is 60 W. Included is a 250 ADC battery breaker, 63 AAC AC input and output breakers, and a 50 AAC generator input breaker.For the Sol-Ark 15k the standby draw is 90 W. Included is a 400 ADC battery breaker with dual terminals, 200 AAC grid input terminals, 200 AAC AC output breaker, and a 100 AAC generator input terminals.
The Sol-Ark 8k-48-STand Sol-Ark 5k-48-ST come with a 5 year warranty, and 10 years optional. The Sol-Ark 12k-Pand Sol-Ark 15k come with a 10 year warranty. Multiple units of the Sol-Ark 12k-P or Sol-Ark 15k can be stacked if more power is needed.
The Sol-Ark 12k-P-EMP is enhanced with Electro Magnetic Pulse (EMP) protection built in and surge suppressors for the input and output circuits. This gives extra protection from strong solar storms or EMP weapons.
Many NEC rapid shutdown systems work with the Sol-Ark. APSystems, Tigo, and IMO FireRaptor can be used for module level shutdown. Either the PV switch on the inverter or a remote normally open switch can be used to trigger rapid shutdown. It's a good idea to use a 48 VDC to 12 VDC power supply at 1.5A or larger to power the APSystems or Tigo rapid shutdown transmitter. Meets UL1741-2010/2018, IEEE1547a-2003/2014, FCC 15 class B, UL1741SA, CA Rule 21, HECO Rule 14H (CA Rule 21 pending for the Sol-Ark 15k).
