  • Page 6: Introduction

    1. Introduction The 3000SP storage inverter is an AC-connected bidirectional electrical energy inverter developed for photovoltaic production systems and domestic storage systems. The inverter can be combined with lithium and lead batteries of different capacities. The system is also compatible with all existing photovoltaic inverters and modules and can be integrated into an existing system or installed together with a new photovoltaic system.
