1.1 Inverter Description
The Solis S6 Hybrid series is designed for residential applications. The inverter can work
with high-voltage lithium ion batteries to maximize self-consumption and provide backup
power if the grid fails and there is not enough PV power to cover load demand.
This inverter can operate in both on-grid and off-grid applications.
The S6 hybrid series consists of the following inverter models: 3.8kW, 5kW, 7.6kW, 10kW,
and 11.4kW. The 3.8-5K models are of a similar but different hardware platform than the
7.6-11.4K models. The inverter comes with an integrated rapid shutdown transmitter.

1. Introduction

● Use the original box to repackage the inverter, seal with adhesive tape with the desiccant
inside the box.
● Store the inverter in a clean and dry place, free of dust and dirt. The storage temperature
must be between -40~158°F and humidity should be between 0 to 100%, non-condensing.
● Do not stack more than two (2) inverters high on a single pallet. Do not stack more than
2 pallets high.
● Keep the box(es) away from corrosive materials to avoid damage to the inverter enclosure.
● Inspect the packaging regularly. If packaging is damaged (wet, pest damages, etc.),
repackage the inverter immediately.
● Store inverters on a flat, hard surface -- not inclined or upside down.
● Do not remove the desiccant packet that is included with the inverter. It is included to
ensure that any residual moisture is absorbed quickly.
● Restarting after a long period of non-use requires the equipment be inspected and, in some
cases, the removal of oxidation and dust that has settled inside the equipment will be
required.
● Perform an annual visual inspection of the inverter box for signs of damage
● If the inverter has been removed from the box and then replaced, put desiccant packets in the
inverter wire box to ensure the internal components stay dry
● Do not store the inverter outside or in a place that does not have environmental controls.
