A unique feature of the SPF5000-ES is its ability to supply AC loads in parallel from solar, grid, and battery simultaneously without dropping to bypass mode when energy reserves are low. Parallel operation for up to 6 units (30kW). Scheduled charging via built-in timer.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e5kW continuous off-grid output\u003c\/li\u003e\n\u003cli\u003e100A integrated MPPT solar charger\u003c\/li\u003e\n\u003cli\u003eMaximum PV input voltage: 450V DC\u003c\/li\u003e\n\u003cli\u003eMPPT operating window: 120V to 450V DC\u003c\/li\u003e\n\u003cli\u003eBattery-independent operation: runs from solar without a battery bank\u003c\/li\u003e\n\u003cli\u003eSupplies AC loads from solar, batteries, and grid simultaneously\u003c\/li\u003e\n\u003cli\u003eDoes not drop to bypass when energy reserves are low: continues supplying from combined sources\u003c\/li\u003e\n\u003cli\u003eWi-Fi monitoring module included\u003c\/li\u003e\n\u003cli\u003eParallel operation: up to 6 units (30kW total)\u003c\/li\u003e\n\u003cli\u003eConfigurable grid or solar input priority\u003c\/li\u003e\n\u003cli\u003eScheduled charging with built-in timer for economy tariff use\u003c\/li\u003e\n\u003cli\u003eBattery equalisation function to extend battery life\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe SPF5000-ES operates at higher PV string voltages than many comparable 48V off-grid inverters, with an MPPT operating window from 120V up to 450V. A minimum of six 300-500W panels in series is recommended to maintain the inverter in the correct operating range. A healthy system typically operates between 300V and 350V under normal conditions.\u003c\/p\u003e\n\u003cp\u003eThe key practical advantage of the SPF5000-ES over conventional off-grid inverters is its ability to combine solar, battery, and grid power to supply loads simultaneously. Rather than switching to bypass mode when the battery is low, the inverter draws from whichever combination of sources is available, maximising use of available solar and minimising grid consumption.\u003c\/p\u003e\n\u003cp\u003eThe scheduled charging timer allows batteries to be charged from the grid during off-peak hours overnight, ensuring the battery bank enters each day fully charged when solar generation will cover the daily demand.\u003c\/p\u003e\n\u003cp\u003eFor 0% VAT supply and installation enquiries, please contact us.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable style=\"width:100%; border-collapse:collapse; border:2px solid #f87c24;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color:#f87c24; color:#ffffff;\"\u003e\n\u003ctd style=\"padding:10px; font-weight:bold;\"\u003eParameter\u003c\/td\u003e\n\u003ctd style=\"padding:10px; font-weight:bold;\"\u003eValue\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #f87c24; padding:8px;\"\u003e\u003cstrong\u003eRated Output Power\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #f87c24; padding:8px;\"\u003e5000W (5kW)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #f87c24; padding:8px;\"\u003e\u003cstrong\u003eBattery Voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #f87c24; padding:8px;\"\u003e48V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #f87c24; padding:8px;\"\u003e\u003cstrong\u003eSolar Charger\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #f87c24; padding:8px;\"\u003e100A MPPT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #f87c24; padding:8px;\"\u003e\u003cstrong\u003eMPPT Operating Range\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #f87c24; padding:8px;\"\u003e120V to 450V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #f87c24; padding:8px;\"\u003e\u003cstrong\u003eMax PV Input Voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #f87c24; padding:8px;\"\u003e450V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #f87c24; padding:8px;\"\u003e\u003cstrong\u003eRecommended Min Panels\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #f87c24; padding:8px;\"\u003e6 x 300-500W in series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #f87c24; padding:8px;\"\u003e\u003cstrong\u003eBattery Independent\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #f87c24; padding:8px;\"\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #f87c24; padding:8px;\"\u003e\u003cstrong\u003eParallel Units\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #f87c24; padding:8px;\"\u003eUp to 6 (30kW total)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #f87c24; padding:8px;\"\u003e\u003cstrong\u003eMonitoring\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #f87c24; padding:8px;\"\u003eWi-Fi (module included)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #f87c24; padding:8px;\"\u003e\u003cstrong\u003eSKU\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #f87c24; padding:8px;\"\u003e002359\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOff-grid homes and properties requiring high PV string voltage operation\u003c\/li\u003e\n\u003cli\u003eInstallations requiring simultaneous solar, battery, and grid supply to loads\u003c\/li\u003e\n\u003cli\u003eScalable off-grid systems expandable via parallel operation\u003c\/li\u003e\n\u003cli\u003eSystems with overnight scheduled battery charging at economy tariff\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation and Safety Notes\u003c\/h3\u003e\n\u003cp\u003eMust be installed by a qualified electrician or solar installer.
