Whilst the modular design facilitates transport to the installation site, the ground must be level, firm and load-bearing (concrete floor recommended). Wall mounting to prevent tipping is strongly recommended at this height. FAQs on the Felicity FLH96050SG01 (30.72 kWh)Which inverter do I need for 6 modules?This is the most critical aspect at this scale: the final charging voltage is close to or above 700 V. You must use an inverter that supports this high battery voltage range (e.g. Deye SUN-10K/12K/15K-SG01HP3 or large Solis hybrid units). Smaller high-voltage inverters, which are only rated for a battery voltage of up to 600 V, are not Compatible!Can I expand the system further?A single tower with 6 modules is generally at its full mechanical and electrical capacity. If you require even more capacity (e.g. 60 kWh), you must set up a second complete tower in parallel and connect it via a combiner box or directly to the inverter (depending on the inverter model).Is installation difficult?The principle (“stacking”) is simple. However, due to the height of the tower (6 modules + top section), you may need a small ladder or a step stool for the upper modules. Furthermore, two people should carry out the assembly to safely lift the 50 kg modules to head height.What happens if a module fails?Thanks to the modular design, there is no need to replace the entire system. A single faulty module can be removed from the tower or replaced. The BMS may then need to be recalibrated to adjust to the new voltage levels.
