One box runs the panels, the battery and the house: solar goes to the home first, the surplus charges the battery, and if the grid drops the backup circuit switches to the battery in under 10 ms.\u003c\/p\u003e\n\u003cp class=\"crx-lede\"\u003eIts rated output current is 15.7 A at 230 V, inside the 16 A a phase that G98 covers, so on its own it needs only a notification to the network operator once it is commissioned. It takes up to 7.2 kWp of panels, Solis's recommended maximum, and uses up to 5.76 kW of their output at any moment; it moves up to 3.6 kW in or out of the battery.\u003c\/p\u003e\n\n\u003ch3 class=\"crx-h\"\u003eS6 3.6kW Plus at a glance\u003c\/h3\u003e\n\u003cdiv class=\"crx-facts\"\u003e\n  \u003cdiv class=\"crx-fact\"\u003e\n\u003cb\u003e3.6 kW\u003c\/b\u003e\u003cspan\u003eGrid and backup output\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003cdiv class=\"crx-fact\"\u003e\n\u003cb\u003e48 V\u003c\/b\u003e\u003cspan\u003eBattery, 40–60 V\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003cdiv class=\"crx-fact\"\u003e\n\u003cb\u003e80 A\u003c\/b\u003e\u003cspan\u003eBattery charge and discharge\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003cdiv class=\"crx-fact\"\u003e\n\u003cb\u003e2 MPPT\u003c\/b\u003e\u003cspan\u003eOne string each, 16 A\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003cdiv class=\"crx-fact\"\u003e\n\u003cb\u003e7.2 kWp\u003c\/b\u003e\u003cspan\u003eRecommended max array\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003cdiv class=\"crx-fact\"\u003e\n\u003cb\u003e5.76 kW\u003c\/b\u003e\u003cspan\u003eMax PV it uses at once\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003cdiv class=\"crx-fact\"\u003e\n\u003cb\u003eIP66\u003c\/b\u003e\u003cspan\u003eIndoor or outdoor\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003cdiv class=\"crx-fact\"\u003e\n\u003cb\u003eG98\u003c\/b\u003e\u003cspan\u003e15.7 A at 230 V\u003c\/span\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\n\u003ch3 class=\"crx-h\"\u003eWhat's in the box\u003c\/h3\u003e\n\u003cp\u003eThis is Solis's packing list for the S6-EH1P(3-8)K-L-PLUS range, from the installation manual (version 1.2, October 2025), with what the installer still has to provide underneath it.\u003c\/p\u003e\n\u003cul class=\"crx-inc\"\u003e\n  \u003cli\u003eThe inverter, its back plate and the two screws that lock it to the plate\u003c\/li\u003e\n  \u003cli\u003eFour expansion bolts for fixing the back plate to the wall\u003c\/li\u003e\n  \u003cli\u003eTwo pairs of MC4 DC connectors, one pair for each string\u003c\/li\u003e\n  \u003cli\u003eThe CT clamp, an ESCT-TA16-100A\/50mA on a 5 m lead.

On today's large-cell panels that 16 A limit is usually the one to check first. The trackers work from 90 V to 435 V, and the inverter starts at 90 V with a 500 V maximum, so a string laid out for a 1,000 V string inverter will over-voltage this one: keep each string's cold-morning open-circuit voltage under 500 V.\u003c\/p\u003e\n\u003cp\u003eTwo PV figures are worth keeping apart. \u003cb\u003e7.2 kWp\u003c\/b\u003e is the largest array Solis recommends, twice the 3.6 kW rating. \u003cb\u003e5.76 kW\u003c\/b\u003e is the most solar power the inverter will take in at any moment, 160% of its rating; on a bright day anything the panels make above that is clipped. Panels rarely reach their full rating in UK conditions, so a 7.2 kWp array mostly hits that cap around midday on the brightest days, and an east\/west split with one roof face on each tracker hits it less.\u003c\/p\u003e\n\n\u003ch3 class=\"crx-h\"\u003eThe battery side\u003c\/h3\u003e\n\u003cp\u003eIt takes any battery between 40 V and 60 V, lithium or lead-acid, on one battery port with a BMS link over CAN or RS485. The 3.6 kW charges and discharges at up to 3.6 kW and 80 A, so check the battery's own continuous rating before counting on the inverter's figure. Solis's IntelliHome batteries list this range as compatible. Inverters built before April 2026 need a firmware update before they are commissioned with an IntelliHome battery.\u003c\/p\u003e\n\u003cp\u003eNo battery yet? Choose \"No battery\" in the setup and it runs as a grid-tied solar inverter, sending any spare solar to the grid when export is allowed, until a battery is added.\u003c\/p\u003e\n\n\u003ch3 class=\"crx-h\"\u003eBackup, generator and off-grid\u003c\/h3\u003e\n\u003cp\u003eThe backup port carries the full 3.6 kW continuously and twice that for 10 seconds, which gives motors, pumps and air conditioning a reliable start, and up to 35 A passes through to the backup circuit while the grid is up. Smart load control sheds less important loads to stretch the battery, and the backup reserve level is adjustable.\u003c\/p\u003e\n\u003cp\u003eA generator can feed it at up to 3.6 kW, alongside the inverter, and it can run off-grid on solar alone. An existing grid-tied PV inverter can be connected to it for export control and off-grid use, and up to six units run in parallel, which is also how Solis builds a three-phase system from this single-phase model.\u003c\/p\u003e\n\n\u003ch3 class=\"crx-h\"\u003eGrid approval\u003c\/h3\u003e\n\u003cdiv class=\"crx-note\"\u003e\n  \u003cdiv\u003e\n    \u003cb\u003eG98: notify the network operator within 28 days\u003c\/b\u003e\n    \u003cp\u003eOn its own the 3.6 kW stays inside G98's 16 A a phase, so the installer tells the network operator within 28 days of commissioning.
