# Italy Villa Solar Storage Case: 4-Unit EXLIPORC Battery Parallel with Deye Inverters

Lombardy, Italy – In the residential solar market across Southern and Central Europe, homeowners with high electricity loads—such as geothermal heat pumps, electric vehicle (EV) charging stations, and extensive domestic appliances—are outgrowing traditional single-battery setups.

This newly commissioned installation in Northern Italy demonstrates how a high-capacity residential microgrid achieves true 24/7 energy independence by combining 4 units of EXLIPORC floor-standing batteries in parallel with a synchronized 3-unit Deye hybrid inverter array.

The client, a large rural villa owner in Northern Italy, previously operated a standard grid-tied rooftop solar array. However, escalating time-of-use tariffs, steep winter heat pump electricity bills, and occasional rural grid outages created significant operational challenges:

• Heavy Power Consumption: High simultaneous peak loads driven by ground-source heating and multiple EV charging ports.
• Low Solar Self-Consumption: Over 60% of daytime solar generation was previously exported back to the grid at low feed-in tariffs, while evening peak power was purchased at premium rates (€0.38+/kWh).
• Need for Seamless Backup: Essential domestic circuits required automated sub-20ms uninterruptible switchover during utility grid disruptions.

To address these demands, the local EPC installation team deployed a modular, high-capacity low-voltage storage configuration:

• Battery Configuration: 4 units of [floor-standing home solar battery storage] installed in a neat parallel line, equipped with heavy-duty caster wheels for flexible equipment room placement.
• Inverter Integration: 3 synchronized wall-mounted Deye hybrid solar inverters directly connected via heavy-duty DC copper cables, enabling high-amperage charge/discharge throughput.
• BMS & Inverter Telemetry: Utilizing standard CAN/RS485 communication protocols, the integrated EXLIPORC smart BMS automatically synchronizes state-of-charge (SOC), voltage, and cell temperatures directly to the Deye master controller.

By implementing [multi-unit parallel residential battery systems], the household expanded total usable capacity while maintaining balanced load distribution across all 4 battery packs.

1. Plug-and-Play hybrid solar inverter battery pairing:
   Pre-programmed Deye communication protocols enabled seamless commissioning within 4 hours, eliminating complex manual firmware bridging.
2. Solar Self-Consumption Increased to 92%:
   Excess daytime generation is fully absorbed by the 4-battery bank, providing complete overnight power for heating and household loads without grid draw.
3. Automated Black-Start & Off-Grid Resiliency:
   During seasonal storms, the system automatically transitions into islanded microgrid mode, supplying continuous three-phase power to critical loads.
4. Fast European Hub Fulfillment:
   All equipment was dispatched directly from EXLIPORC’s European Poland central warehouse, arriving at the Italian installation site within 4 business days under DDP terms with zero customs friction.
