Off-grid inverter Qoltec 53887 solar inverter 10 kVA Lithium Polymer Black

The Qoltec 53887 off-grid hybrid inverter converts DC energy from PV modules into AC power for household appliances. It functions as both a solar charger and a battery charger, includes a built-in 100A MPPT charge controller, and features a multifunctional LCD display for monitoring operating data. The unit supports connection of an optional Wi‑Fi module, does not support BMS, and is designed to operate in off-grid mode with active cooling and protection against overheating, overload and short circuit.

Advantages

The inverter provides a maximum output of 10 kVA while accepting a minimum input voltage of 90 V, and is compatible with Lithium Polymer (LiPo) battery systems. Its integrated 100A MPPT regulator optimizes solar charging, the LCD display enables continuous system monitoring, and the device includes essential safety protections. The inverter is compact and relatively lightweight (10.5 kg), making installation and handling easier in off-grid PV systems.

Suitable for

• Off-grid homes and cabins requiring a 10 kVA inverter
• Small commercial sites or workshops without a stable mains connection
• Solar PV systems with LiPo battery storage
• Installations needing MPPT solar charging and monitoring via LCD (Wi‑Fi optional)

How to use

Install the Qoltec 53887 according to local electrical codes and the manufacturer's installation instructions, connecting PV modules to the MPPT input, the LiPo battery bank to the battery terminals, and AC loads to the inverter output. Configure system parameters and monitor operating data via the built-in LCD display. If remote monitoring is required, install the compatible Wi‑Fi module and follow the setup procedure. Ensure proper ventilation for active cooling and verify all protective settings before putting the system into regular operation.

Recommendations

For reliable long-term performance, use a compatible Lithium Polymer battery bank sized according to your load profile, keep the inverter in a ventilated, dust-free location, and perform regular inspections of PV connections and battery condition. Do not connect a battery management system (BMS) expecting supported communication, as BMS is not supported by this model.
