Grid-tied, hybrid or off-grid 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 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. Standby draw is 60 W. Included is a 250 ADC battery breaker, 63 Amp AC input and output breakers, and a 50 Amp AC generator input breaker. 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.
The Sol-Ark 8k-48-ST comes with a 5 year warranty, 10 years optional. The Sol-Ark 12k-P Comes with a 10 year warranty. Multiple units of the Sol-Ark 12k-P can be stacked if more power is needed.
Many NEC rapid shutdown systems work with the Sol-Ark. APSystems, Tigo, and IMO FireRaptor can be used for module level shutdown. Either the switch on the inverter or a remote normally open switch can be used to trigger rapid shutdown. Electro Magnetic Pulse hardening is an available option.
The inverter can put out 9000 watts of AC into the grid. This is kept at 9kw so the inverter can be used with a 200 amp electrical panel. 9000 divided by 240 volts equals 37.5 amps.
This inverter is transformerless creating light weight, easier cooling and high efficiency.
There’s also a breaker for using a dump load. If the battery is full and there’s no grid available electricity can be routed to a dump load instead of being wasted.
