About this deal
Support the public and businesses to achieve an optimal sustainable power solution for their mobile applications; EG4 18KPV Hybrid Inverter | All-In-One Solar Inverter | 18000W PV Input | 12000W Output | 48V 120/240V Split Phase | EG4 18KPV-12LV
48V DC to 240V AC Power Inverters | Off-Grid/ UPS/ Industrial
The DC-to-AC pure sine-wave inverter delivers network-grade power. Its automatic line-to-battery transfer switch and integrated charging system allow the unit to work as an extended-run UPS, standalone AC power source or vehicle inverter. It delivers 4000W of continuous power, 6000W up to one minute or 8000W of peak power up to 10 seconds during equipment startup or cycling. An automatic overload detector, cooling fan and resettable AC circuit breakers protect the unit from damage. Features: Smart Remote Control, Automatic Generator Starting (AGS), Suitable for different kinds of batteries. Automatic overload detector, built-in cooling fan and resettable AC circuit breakers protect unit from damageA small battery inverter to manage an island grid + a large grid-tie PV system will run an A/C off-grid just fine. My central A/C for ~ 1000sf of house has 15A 230V breaker, so figure 3kW when operating. A 6 kW GT PV system and a battery inverter with 100 Ah 48V would be sufficient.

Usually, if the appliance or an equivalent can be run by direct current and low voltage from a battery bank, the power consumption will be less. Some appliances may not like the wave form from a particular inverter. Or you may find that the inverter causes a hum on sound equipment (stereo, TV, etc). It is a fairly costly item that may need the occasional service or repair. For all of these reasons it makes sense to have as much as you can powered directly by the battery bank and only use the appropriate sized inverter for those appliances that you could not find an adequate low voltage version of. Heavy Loads on an inverter? If you want to store enough solar to run that AC for 5hrs then you need ANOTHER 7kw of solar just to "save it" (total solar ~20kw) Easy enough to wire an electric dryer for 115V, 1/4 the wattage. What I plan to do (considering my large PV capacity), is leave it wired for 230V but put a load-shed relay in the phase that only goes to heating element. Motor/timer will continue to be powered, but heating element will turn on/off depending on availability of surplus power. The significant advantages of the XW Pro design include a robust transformer as part of an isolated inverter design. The toroidal transformer provides industry-best surge capability with a high overload rating (2x power). It also has quieter operation, superior temperature range, and better efficiency than other types of transformers. As a result, the XW Pro can start heavy-duty tools such as air compressors, water pumps, sump pumps, air conditioners, and motor loads. It can also run multiple appliances on a single leg. One of them can probably power your loads, with a suitably sized 120/240V transformer. But better to get two for split-phase.I have the 24V/2000W WZRELB unit. Be advised that they have ZERO surge. If you have need to run motors that may exceed 3000W of surge, unlikely that the unit can handle them. of peak power up to 10 sec. to accommodate surge power demands during equipment startup and cycling As it turns out 20kw is about the size that I see a lot of "whole house" systems get that maintain an expectation of "normal" grid power life. Northern NSW (Tweed Heads to Iluka, including Evans Head, Byron Bay and Ballina); the Far North Coast Hinterland (Yamba via Lismore to Murwillumbah) and out West (Casino to Tenterfield, including Drake and Tabulam, as well as Woodenbong and Bonalbo) Sigineer Power produces 48v inverter charger from 2,000 watts to 18,000 watts with true sine wave output and built-in transfer switches.
