48V Hybrid Inverter · Transformer-Free · Parallels Up to 16
The EG4 6000XP converts stored DC power from a 48V lithium battery bank into full-strength 120/240V split-phase household electricity, backed by up to 8,000W of dual-MPPT solar input. Its transformer-free architecture trims weight and standby losses compared to traditional inverter designs, while a sub-15ms transfer time keeps backup power switching close to seamless.


Rated for 6,000W of continuous output with up to 12,000W of surge headroom (3.5 sec) to start motors and pumps without tripping.
A lighter, more efficient architecture than traditional transformer-based inverters, with less standby power lost as heat.
Two independent MPPT trackers pull up to 8,000W combined, adjusting continuously as sunlight shifts through the day.
Switches to battery power in under 15 milliseconds on its own, keeping sensitive electronics running through a grid drop without a hard reboot.
Scales far beyond a single-home setup — stack units together for larger properties or commercial-scale off-grid installations.
Integrated circuit breakers simplify installation and add a layer of protection against faults right out of the box.
Track production, consumption, and battery status remotely, with support for load control, AC coupling, and peak shaving.
Closed-loop communication with the full BigBattery and EG4 battery lineups, without being locked to a single battery model.
The "6000" in its name is the continuous output rating; the "8kPV" is what the solar side can handle — up to 8,000W across two independent MPPT trackers, tuned separately as clouds and sun angle change through the day. A transformer-free design keeps the unit lighter than older inverter architectures and cuts down on the standby losses that come from an always-on transformer core.
Where it really separates from a typical single-home inverter is scale: up to 16 units can run in parallel, which puts genuinely large installations — bigger homes, workshops, small commercial sites — within reach of the same platform, without switching to a different product line. Built-in breakers, remote monitoring, and a sub-15ms transfer to battery power round out a unit that's meant to be installed once and left alone.

Built around 48V lithium battery banks (46.4–60Vdc), with closed-loop communication across the full BigBattery and EG4 battery lineups rather than a single approved model. Commonly paired batteries include:

"6000" is the continuous AC output rating in watts (6,000W). "8kPV" refers to the maximum solar array input the inverter can handle — up to 8,000W across its two MPPT trackers. The two numbers describe different sides of the same unit: what it outputs versus what it can accept from panels.
It depends on your total connected load. At 6,000W continuous (12,000W surge) it covers most efficient homes and cabins comfortably, but a full load calculation is worth doing before sizing your system — especially with well pumps, electric heat, or several large appliances running together.
Any 48V lithium battery bank in the BigBattery or EG4 lineup works via closed-loop communication, including NEXUS, ETHOS, HUSKY2 INV, and EG4's 280Ah and 314Ah packs.
No — it's rated IP20, meaning indoor or fully enclosed installation only, such as a garage, utility room, or dedicated power shed.
Up to 16 units can be paralleled on this platform, which is enough headroom to scale from a single home up to larger or commercial-style off-grid installations without changing product lines.
Given the voltages and currents involved, installation should be handled by a qualified, licensed electrician or solar installer familiar with your local code requirements.
