UL9540A is the fire-propagation test that many jurisdictions now ask for on indoor energy storage, and it is the reason to choose this over the standard ALPHA 5.\u003c\/p\u003e\u003ch2\u003eWhy this battery\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e5,120Wh per battery - about 7% more than the standard ALPHA 5's 4,800Wh, in a slightly smaller 3U footprint.\u003c\/li\u003e\n\u003cli\u003eUL1973, UL9540A, FCC, UN38.3 and MSDS. If your building department or insurer asks for a listed indoor storage battery, this is the one in the range that satisfies it.\u003c\/li\u003e\n\u003cli\u003e10-year warranty, against no published term on the standard ALPHA 5.\u003c\/li\u003e\n\u003cli\u003e7,000+ cycles from grade-A welded prismatic cells at 80% depth of discharge.\u003c\/li\u003e\n\u003cli\u003eIntegrated 150W heater: charging is blocked below 32°F, heating starts below 41°F and stops above 50°F. The standard ALPHA 5 has no heater at all, so in an unheated garage the PRO is the only one of the two that will charge through winter.\u003c\/li\u003e\n\u003cli\u003eWi-Fi and Bluetooth monitoring plus a front-panel LCD and LED status display, so you can read state of charge without a phone.\u003c\/li\u003e\n\u003cli\u003eRS485, RS232 and CAN ports with published protocol codes for Pylon, Growatt, Victron, Sol-Ark, Schneider, LuxPower, GoodWe, Solis, Senergy, SMA and Megarevo. Set the protocol code in the inverter settings to match.\u003c\/li\u003e\n\u003cli\u003eParallels up to 30 units - far beyond the six-battery rack - so the same battery covers a house and a light commercial installation.\u003c\/li\u003e\n\u003cli\u003eWorth noting: it is IP21, meaning drip-protected but still indoor-only, and it is 100.9 lb per battery.
