It does not need solar panels to operate, and works with both lithium-ion and lead-acid batteries. A CT current transformer is included for managing grid power flow.\u003c\/p\u003e\u003ch2\u003eSolis AC coupled inverter key features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower\u003c\/strong\u003e, 3kW single phase AC coupled inverter and battery charger\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery compatibility\u003c\/strong\u003e, lithium-ion and lead-acid, 40 to 60V, 50 to 2000Ah\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCharge\/discharge current\u003c\/strong\u003e, max 60A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery communication\u003c\/strong\u003e, CAN, for lithium battery BMS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCooling\u003c\/strong\u003e, natural convection, no external fan\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrid compliance\u003c\/strong\u003e, G98\/G99 for UK grid connection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions and weight\u003c\/strong\u003e, 405 x 510 x 150mm, 12.1kg\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eProduct overview\u003c\/h2\u003e\u003cp\u003eThe S5-EA1P3K-L lets homeowners and businesses with an existing grid-tied solar installation add battery storage without replacing their current inverter. It connects on the AC side of the system, charging the battery from solar generation or from the grid on an off-peak tariff, then discharging to supply loads during peak periods or a grid outage.\u003c\/p\u003e\u003cp\u003eFor properties without solar panels, the inverter can charge a battery bank purely from the mains at a low-cost overnight tariff and discharge during peak hours. No PV installation is required, and panels can be added later. Natural convection cooling removes the external fan found on many inverter-chargers, cutting noise and one common source of mechanical failure.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eAdding battery storage to an existing grid-tied solar PV system\u003c\/li\u003e\n\u003cli\u003eOff-peak tariff charging with peak-hour discharge, no solar panels needed\u003c\/li\u003e\n\u003cli\u003eSelf-consumption and backup power for residential and commercial properties\u003c\/li\u003e\n\u003cli\u003eAC coupling with any brand of existing grid-tied inverter\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation and safety notes\u003c\/h2\u003e\u003cp\u003eThis inverter must be installed by a qualified electrician or MCS-accredited solar installer.
