iStore Commercial Hybrid Solar Inverter
Smart string inverters for commercial solar
The iStore IS-INV-29900 / 40000-3PH Smart String inverter is renowned for its intelligence, efficiency, safety, and reliability, making it among the top choices for 8-String inverters on the market due to its impressive power capabilities
The iStore IS-INV-29900/40000-3PH stands out as one of the most advanced inverters available, thanks to its 8-Strings intelligent monitoring, rapid troubleshooting capabilities, Power Line Communication (PLC), and Smart I-V Curve Diagnosis support.
Efficient
4MPPT per unit effectively reduces string mismatch, offering a maximum efficiency of 98.6% (European efficiency of 98.4%) the iStore IS-INV-29900 / 40000-3PH offers premier efficiency, and with intelligent control systems, a single panel being shaded or obscured does not compromise the entirety of your system, meaning that you can install more panels on your roof than with other systems, generating even more efficient power.
Safe
The iStore IS-INV-29900 / 40000-3PH Integrated DC Switch enhances both safety and maintenance convenience. Its fuse-free design and integrated Residual Current Monitoring Unit (RCMU) set it apart as one of the market’s safest systems.
iStore Solar Battery
The iStore energy storage system is here. The perfect option to couple with any iStore inverter, the iStore Solar Battery can be modified to suit your energy needs, however large they may be.
Thanks to its modular design, rather than having to buy an additional battery if you want to expand your home’s energy storage reserves, all you need to do is add another battery block to your iStore Solar Battery, saving you money and space. Due to this clever design, the iStore can scale in size anywhere from 5 kWh all the way to 30 kWh.
The iStore solar battery consists of stackable modules, each weighing 50kg, with a capacity of 5kWh. By connecting three modules together, you can create a 15kWh battery.
Furthermore, two sets of these 15kWh batteries can be connected in parallel to achieve a maximum capacity of 30kWh. Each battery stack can reach 5kW output power and 7kW surge power for 10s
- Modular design allows for flexible investment
- Perfect compatibility with both single and three phase iStore Hybrid inverters
- More usable energy with 100% depth of discharge
