Project Background<\/h3>\n\n\n\n

Project Location:<\/strong>\u00a0Philippines (remote island \/ rural area \/ off-grid region)<\/p>\n\n\n\n

System Type:<\/strong> Pure off-grid solar + storage system (independent microgrid)<\/p>\n\n\n\n

Core Requirement:<\/strong> Provide 24\/7 uninterrupted power supply with no grid support, relying entirely on PV + battery storage.<\/p>\n\n\n\n

Deye Inverter Requirements<\/h4>\n\n\n\n

For pure off-grid applications, the Deye inverter must support parallel operation in off-grid mode. Furthermore, you must configure the system with a master\/slave setup.<\/p>\n\n\n\n

Selected Model:<\/strong>\u00a0Deye SUN-10K-SG06LP1-EU \u2013 single-phase 10kW<\/a>, supports off-grid parallel connection.<\/p>\n\n\n\n

Installation Key Points<\/h3>\n\n\n\n

1. Wall Mounting<\/h4>\n\n\n\n

First, ensure the wall structure meets the requirements. The wall must be made of concrete or solid brick and must support a load capacity of at least 700kg.<\/p>\n\n\n\n

Next, arrange the batteries in layers, keeping the bottom of each unit at least 300mm above the floor.<\/p>\n\n\n\n

For the inverters, install them side by side with a minimum clearance of 300mm between units.<\/p>\n\n\n\n

Finally, connect all equipment enclosures to a common grounding system, ensuring the grounding resistance stays below 4\u03a9.<\/p>\n\n\n\n

2. Inverter Parallel Wiring \u2013 Critical Step<\/h4>\n\n\n\n

For the parallel connection, follow these steps:<\/p>\n\n\n\n

First, connect the parallel communication ports using Deye’s dedicated communication cables.<\/p>\n\n\n\n

Then, set the master and slave units via the software interface or DIP switches according to the system configuration.<\/p>\n\n\n\n

After that, connect the AC outputs \u2013 tie the L (live), N (neutral), and PE (protective earth) conductors from both inverters together, and then route them to the main distribution panel.<\/p>\n\n\n\n
