Pending Approvals: for: HECO, Canada, & PREPA Approved for Puerto Rico 120/240 & 208V

CA, HI, PR customers: CEC listing, CA Rule 21 compliance, SGIP, HECO and PREPA certifications are expected in November 2022. These state and local specific requirements will need to be in place before a Sol-Ark 15K inverter can be permitted and pass inspection for interconnection with the grid.

Electronics Certified Safety by SGS Labs to NEC & UL Specs - NEC 690.4B & NEC 705.4/6

Grid Sell Back - UL1741-2010/2018, IEE-E1547a-2003/2014, FCC 15 Class B, UL1741SB

All Hybrid Inverter PV Systems will need rapid shutdown. The IMO BG10P34-11 remote shutdown button is an outdoor initiation switch that can be used to trigger PV system rapid shutdown.
IMO RSD Button BG10P34-11 > Rapid Shutdown Button compatible with APsmart Rapid Shutdown System

IEEE 1547-2018 requires the local communications interface to remain available whenever the DER is operating. This indirectly creates a requirement for the IQ Gateway not to reboot during and following a low voltage ride through event. The IQ Gateway hardware was redesigned to meet this requirement so installers must only choose from the list of supported hardware and be running software versions 7.3.460 or later to be fully compliant.

Helpful Hint with Sol-Ark hybrid inverters: Unlike most string inverters - Sol-Ark hybrid inverter solution will not have a complete power loss for a series string of modules if one of the panels goes bad (stops producing) *** so as long the total voltage of the remaining panel meets or exceeds the min MPPT voltage range of 150VDC.

Lithium iron phosphate battery The lithium iron phosphate battery (LiFePO4 or LFP) is the safest of the mainstream lithium battery types. A single LFP cell has a nominal voltage of 3.2V. A 51.2V LFP battery consists of 16 cells connected in series. LFP is the chemistry of choice for very demanding applications. Some of its features are:
  • Rugged - It can operate in deficit mode during long periods of time.
  • High round trip efficiency.
  • High energy density - More capacity with less weight and volume.
  • High charge and discharge currents - Fast charges and discharges are possible.
  • Flexible charge voltages.

  • The system can automatically manage charge and discharge state and balance current and voltage of each cell.
  • Flexible configuration, multiple battery modules can be stacked for expanding output and Capacity.
  • Adopted self-cooling mode efficiently reduces any system noise.
  • The module has less self-discharge, up to 6 months without charging on a shelf, no memory effect, with excellent performance of shallow charge and discharge.
  • Working temperature range is from -10 to 55℃ (14F-131F) , (Charging 0~45℃ (32-113F); discharging -10~55℃ (14F-131F) )with excellent discharge performance and cycle life.
  • Small volume, light weight, plug-in embedded design modules, are easy to install and maintain.
