EG4 is the brand of EG4 Electronics LLC of Sulphur Springs, Texas, part of Energy Access Innovations with its sister company Signature Solar.
It sells with a cart through Signature Solar at signaturesolar.com and through approved distributors and dealers such as Current Connected, Shop Solar and BigBattery, while eg4electronics.com has no cart.
The EG4 12kPV, model IV-8000-HYB-AW (followed by 00-99 on the label), is a 48 V all-in-one hybrid inverter charger that EG4's Connections & Paralleling Guide says can function fully in off-grid only mode, with no utility or generator: 8,000 W continuous pure sine output at 120/240 V split phase (or 120/208 V) from one unit, 4,000 W per 120 V line, and peak ratings of 16 kW for 0.5 s, 12 kW for 1 s, 10 kW for 1 minute and 8.8 kW for 12 minutes, with a 195 A locked-rotor rating. EG4 rates battery-to-AC efficiency at 94% and standby idle consumption under 55 W; transfer is 20 ms by default and 10 ms selectable on a single unit, 20 ms in parallel. Solar input is two MPPT trackers with two strings each, 25 A per tracker, 100-600 VDC input range, a 120-500 V MPPT range, 12,000 W utilized and 15,000 W recommended. AC input is 8,000 W, with 80 A grid and generator passthrough by the spec sheet (the Connections & Paralleling Guide says 50 A on the generator port), and the battery side is 48 V (40-60 V) lithium or lead-acid at up to 167 A charge or discharge, with CAN and RS485 closed-loop communication with EG4 and other listed batteries. Up to 10 units run in parallel (80 kW). The grid-tie functions, export to grid, zero export, peak shaving and AC coupling, earn nothing for an off-grid buyer. It measures 29.5 x 20.5 x 11.2 in (750 x 520 x 285 mm), weighs 110 lb (50 kg), has a NEMA 4X enclosure, runs from -13 to 140 F and is rated under 50 dB at 3 ft. In the box: the inverter, wall bracket, mounting template, two current transformers, the Wi-Fi dongle, 6 ft battery and parallel communication cables, RJ45 connectors, L-brackets, expansion bolts, screws and keys. The 10-year warranty must be registered within the first year, or the buyer must show proof of purchase from an EG4 authorized distributor, to remain valid. It is also sold in Signature Solar's EG4 Home Power Bundle (BNDL-E0012) with a WallMount battery at $7,520.97. EG4 sells through its sister company Signature Solar.
