Скачать или смотреть Solar Container: Low cost, reliable 3Phase power for commercial and large residential installations

The benefits of three phase power over single or split phase are compelling: Higher power capacity, smoother power delivery, smaller equipment for the same power, greater efficiency, uniform torque, more flexibility, better fault tolerance--and the list goes on. For commercial and industrial use there's no question--if you can get it, you want it. Even large residential installations benefit. It's actually feasible to provide three-phase power either grid connected or off-grid from a moderate-scale solar installation--and the installation can scale up as necessary. This experimental installation will power my shop, which is wired and supplied with three-phase grid power. The aim is ultra-reliable power even in the event of protracted utility outages.

The hybrid inverter we have chosen is the EG4 18kPV Hybrid Inverter that we purchased from Signature Solar, an all-an-one Solar Inverter with 18000 watts of Photovoltaic panel input and 12000W of 120/240V Split Phase AC Output. The 18K has three independent mppt controllers enabling mixing of panels and mounting locations. After months of research these are the systems we chose for this project. https://signaturesolar.com/eg4-18kpv-...

The Batteries we have chosen, also from Signature Solar, are the EG4 PowerPro Wall Mount All Weather 48V 280Ah 14.3kWh LiFePO4 Lithium Battery. Other 48V solutions, particularly rack mount systems, are more suitable for smaller installations or installations where smaller units of modularity is beneficial, but for our system, the lower cost per KWh, ease of installation, ability to scale rapidly, and appearance made wall mount batteries preferable. https://signaturesolar.com/eg4-powerp...

The solar panels we are using are Aptos 370 watt bifacial panels. These panels are 370W Bifacial Solar Panel (Black) and provide up to 480W with Bifacial Gain. We bought a full pallet (31 panels) and will be buying more if they continue to be available. At $.28 per watt these are an amazing bargain, one pallet is 11470 watts (11.47KW) before bifacial gain. The panels are also available from signature solar in lots of ten. https://signaturesolar.com/11-47kw-pa...

For managing the wiring we are using the EG4 PowerPro Conduit Box which fits perfectly between the 18K inverter and both styles of wallmount battery that Signature Solar carries: https://signaturesolar.com/eg4-powerp...

To connect the batteries in parallel we are adding EG4 paralleling cable which come with the high current plugs already installed: https://signaturesolar.com/eg4-powerp...
