The Solis S6-EH3P10K-NV-YD-L is a 10kW three-phase, low-voltage (48V) hybrid inverter from the
Solis S6 energy storage range, designed for large residential and light commercial solar-plus-battery systems.
It pairs 2 MPPTs supporting up to 16kW of usable PV input with a high-current 48V battery
interface (up to 220A charge/discharge), compatible with a wide range of lithium and lead-acid battery brands.
Built-in features include dual backup ports, generator compatibility, sub-10ms backup
switching, and support for unbalanced and half-wave loads on both grid and backup circuits.

Max Charge/Discharge
Qualified Installation Required
This is a mains-connected, three-phase hybrid inverter with high DC battery currents. Installation, wiring and commissioning must be carried out by a qualified, competent electrician in accordance with UK wiring regulations and G98/G99 grid connection requirements.
Low Voltage Battery Platform
This is the 48V (40–60V) low-voltage battery variant of the Solis S6 hybrid range — confirm battery compatibility before ordering, as Solis also offers high-voltage S6 inverters that are not interchangeable with 48V battery banks.
Model Naming Note
The part number SOL-S6-EH3P10K-NV-YD-L-UK corresponds to the manufacturer's S6-EH3P10K02-NV-YD-L model, where 'K02' denotes the 2-MPPT configuration; 'NV' indicates the normal (400V) grid voltage variant and 'YD' indicates the display-equipped version.
Dual Backup Ports
Two independent backup outputs allow critical and non-critical loads to be controlled separately, so essential circuits stay powered during an outage while non-essential loads can be shed automatically.
Generator Compatibility
A dedicated generator input extends backup duration during extended grid outages, recharging the battery or directly supporting loads when solar generation and stored energy aren't enough.
High-Current 48V Battery Interface
Supporting up to 220A of charge/discharge current at 40–60V, the inverter can move a full 10kW to and from the battery quickly, making the most of surplus solar generation before it's exported.
200% Overload for 10 Seconds
Off-grid surge handling of double the rated output for 10 seconds supports the inrush demands of motors, pumps and air conditioning compressors without tripping the inverter.
Unbalanced and Half-Wave Load Support
Both the grid and backup outputs can supply unbalanced three-phase and half-wave loads, giving installers flexibility where a property's circuits aren't evenly distributed across phases.
Sub-10ms Backup Switching
A backup switch time of under 10 milliseconds means most sensitive electronics and control equipment ride through a grid outage transition without interruption or reset.

What battery voltage does the S6-EH3P10K-NV-YD-L require?
This is the low-voltage 48V variant of the Solis S6 hybrid range, operating across a battery voltage range of 40–60V. It is not compatible with Solis's high-voltage S6 battery systems.
How much PV input can this inverter handle?
It supports up to 16kW of usable PV input power across 2 MPPTs and up to 4 strings, with a maximum input voltage of 1000V and max input current of 40A per MPPT.
Can I run motors or air conditioning off-grid on this inverter?
Yes, it supports 200% overload for 10 seconds in off-grid mode, which helps handle the inrush current of motors, pumps and air conditioning compressors on startup.
Does it support generator backup?
Yes, a dedicated generator input rated to 10kW allows a backup generator to extend runtime or recharge the battery during extended outages.
How fast does the backup supply switch over during an outage?
The backup switch time is under 10 milliseconds, fast enough that most sensitive electronic loads continue running through the transition.
What is the difference between the two backup ports?
The dual backup ports allow critical and non-critical loads to be wired and controlled separately, so essential circuits keep running while less important loads can be automatically shed to conserve battery capacity.
