The Solis S6-EH1P6K-L-PLUS is a 6kW single-phase hybrid solar inverter with two MPPT trackers, 96.2% maximum efficiency, and a 5-year warranty. It accepts up to 12kW of PV input, works with both lithium-ion and lead-acid batteries at 40-60V, and handles up to 135A charge/discharge the largest single-phase hybrid in the Solis range.
6kW is the ceiling of single-phase residential, and this is the hybrid version. A grid-tied inverter exports your surplus and then goes dead the moment the grid drops, leaving you dark under a roof full of panels. This hybrid routes power three ways: to your home, to your battery, and to the grid. When the supply fails, your house keeps running. For a large villa with heavy air-conditioning load in an area with frequent outages, that is the entire reason to choose hybrid over on-grid.
12kW of PV input on a 6kW inverter double the nameplate. This 2:1 DC ratio, consistent across the Solis residential hybrids, changes what you can build on a home roof. Panels rarely produce rated output in real conditions, so a 12kW array on this 6kW inverter generates through far more of the day meaningfully more in early morning and late afternoon, and much better under monsoon cloud. For a household with roof space and a fixed inverter budget, that headroom converts directly into extra annual units.
135A charge/discharge the largest single-phase battery capability in the range. Charge current scales across the Solis residential hybrids (70A at 3kW, 112A at 5kW, 135A here), and at 135A this supports the largest bank and the fastest charging of the single-phase units. That matters for a big home: a bank sized to run substantial load overnight needs to refill within a single day's generation window, and a higher charge current is what makes that possible. It accepts both lithium-ion and lead-acid at 40-60V, so you are not locked in lead-acid for lower upfront cost, lithium for longer life and daily cycling.
The battery is what sizes the system. A hybrid without a battery is an expensive on-grid inverter you have paid for backup you are not using. Sizing the bank against your actual critical load and required backup duration is the decision that matters most. Tell our team which circuits must stay live and for how long, and we will size it against that rather than selling you a round number.
A note on single-phase at 6kW. This is near the practical ceiling for a single-phase connection. If your home has three-phase supply, a three-phase hybrid will suit you better at this rating. Tell our team your connection type and we will confirm this single-phase unit fits, or point you to a three-phase alternative getting that right before you order avoids the most expensive mistake at this capacity.
Two MPPT trackers. Each handles 16A operating current (20A short-circuit) across a 90-435V range, so a roof facing two directions, or with a section shaded through the afternoon, still generates properly each string managed separately rather than dragged to the weakest.
Sizing it correctly. A 6kW inverter suits an array up to 12kW roughly 12 to 24 panels at 500W. The battery is the second decision: too small and it dies mid-outage, too large and it sits depreciating. Tell our team your monthly bill, your critical load, and how long you need backup, and we will size the whole system.
SolarClue is India's managed solar marketplace. Our team confirms this inverter matches your panel array, your single-phase supply, your battery choice and your DISCOM's rules before you order, and handles your PM Surya Ghar subsidy application if your system qualifies. Compare it against Deye, Growatt and Lux Power hybrids on our platform we will tell you which suits your home, not which we are holding. You book with a token payment rather than the full amount upfront. Supply and installation are coordinated through verified partners, and we handle Solis warranty support afterwards.
