The most powerful single-phase inverter & charger ever made. 8kW Continuous AC Output Power

The Conversol Off Grid Solar Inverter with integrated battery charger is a fast, accurate and reliable charger for lead-acid, lithium-ion and LifePO4 batteries. Its 8kw pure sinewave output is capable of powering an entire house, yet it’s still compact and weighs only 18kg. Labeled terminals make identification and installation easier while changing colours make operation status obvious.

This Conversol Inverter includes 3 sets of power cables and power ports: AC output, two independent MPPT chargers for solar panels and 48V battery terminals. It can connect to a grid or generator for uninterrupted power and operate in off-grid mode to supply AC power for large appliances, including air conditioners and water pumps. This inverter can be controlled from around the globe with an integrated Wi-Fi module and has an extended warranty for up to 5 years.

With a Timer Setting for Charging whenever you want.

The inverter is ideal for scheduled charging thanks to the integrated timer, the user can set a specific charging window to re-charge the batteries when the electricity cost is lower.
