Common in grid tied installs and less common in DIY off grid, which shows in how thin the pairing conversation is. The 600 volt PV input is generous for the money.

What this inverter will and will not do
- It works alongside the utility, which means an interconnection agreement, a permit, and an inspection in most jurisdictions. Budget months, not weeks, for that process.
- Output is single phase 120 V. A well pump, an electric dryer, or anything else expecting 240 V needs an autotransformer or a different inverter.
- Battery communication runs over CAN, RS485, and closed loop still depends on both sides agreeing on a message format rather than only on a bus standard.
Sizing a battery bank for it
This inverter delivers up to 125 amps of charge current, and that figure, not your daily energy use, sets the minimum pack count. Every battery below is shown at the smallest bank that can absorb the full charge rate.

Fuse and cable for the battery run
Running flat out this inverter pulls about 125 amps at 48 volts, and a surge takes it to roughly 188 amps. Size the protection for the peak, not the average: a 175 amp Class T fuse at the battery positive terminal and 2/0 AWG cable on the battery run. Class T rather than a standard fuse because a 48 volt lithium bank can deliver enough short circuit current to arc across a fuse that lacks the interrupt rating. Confirm the sizing against your installation manual, which accounts for run length and ambient temperature.
Communication
No manufacturer document tracked here names a specific battery for closed-loop operation with this inverter.
Where the figures come from
Manufacturer documents: Solis product documentation. Figures here should be read against the revision that covers your serial number, because manufacturers revise specifications without changing the model name.

Questions people actually ask
How many batteries does the Solis S6-EH1P6K-L need?
Enough packs to accept 125 amps of charge current. With a 100 amp rack battery that is 2 of them. Fewer will run the system perfectly well with the charge rate capped in settings, and capping it costs you charging speed on short winter days.
What size fuse and cable does the Solis S6-EH1P6K-L need?
It draws about 125 amps continuously at 48 volts and roughly 188 amps during a surge. That points at a 175 amp Class T fuse and 2/0 AWG cable for the battery run, sized for the fuse rather than the average load. Confirm against the figure in your installation manual, which accounts for run length and ambient temperature.
Which batteries have a documented pairing with the Solis S6-EH1P6K-L?
None of the batteries tracked here have a manufacturer document naming this inverter for closed-loop operation. That is a documentation gap, not a verdict on the hardware.
Can the Solis S6-EH1P6K-L run a well pump?
It surges to 9,000 watts, about 188 amps from the battery. Whether the pump starts depends on the pack as much as the inverter, because the BMS is what interrupts a surge it is not rated for. The pairing pages check that figure per battery. A bank of 2 Pylontech US3000C is the smallest configuration on this site with a published surge rating that covers it.
