3KW Offgrid, 4 Power Sources, 9000W Peak, Split-Phase, Wifi

Description: The ST3000W-OGSPH is an off-grid industrial-grade inverter that is powered by anyone of, or a combination of 3 power sources: the utility grid (or generator), battery, and solar energy, hence termed hybrid inverter. It is a split-phase inverter, a common wiring standard in USA households.. The inverter output has 120Vac (tapped from L1 + N or L2 + N) and 240Vac (L1 + L2), and a 120Vac universal socket. Low-frequency inverters, like this ST3000W-OGSPH, are more robust, has longer lifespan than high-frequency inverters, especially so when used with inductive loads (e.g., well pumps, fridge, motors, aircon). The battery for ST3000W-OGSPH must be 48Vdc. Its peak power is 9000W. Advantages over competitors: Works with USA, Europe, and Asian grid voltages (frequency auto-sense). Using one of this inverter, your wiring decides types of output, either 120Vac or 240Vac or both simultaneosuly. Competitors would required two of their units to achieve 240Vac, raising system cost and points of failure. Built-in Input Switches for Solar, Battery, and grid/AC Input.This saves you the space needed, cost, and installation time to buy separate switches. Wifi monitoring of current and historical power generated. Not all competitors' inverter include this feaure. 48V battery input provides a higher surge capacity, to 9000W. This is useful for inductive loads startup, e.g., aircon, fridge, well water pumps, and other motors. Low power consumption when inverter is idle (22W) Joint solar/grid battery charging current to 90A. Low frequency (transformer) inverters like this one are more robust, albeit twice as heavy as an industrial-grade inverter. High frequency inverters get fried easily when used frequently with inductive loads. If you have many inductive loads, this low-frequency inverter will be 3-5x more lasting than high frequency inverters. Future proof your lower wattage inverter, eg, 1000W to be upgraded to 3000W. This inverter will future proof your lower-wattage system, lowering total system cost over time.

Protection Multiple, see User Manual's Technical Specifications Weight 47 lbs Dimensions 20 x 14 x 7 inches Modes of Operation All 3 modes can have grid, solar, and battery connected simultaneously. But each mode varies in behavior. This inverter can run with solar alone (see solar fluctuations/limitations below). Utility/Mains Priority - aka UPS (uninterrupted power supply), if grid fails battery kicks in automatically This is the default and recommended mode. Utility wiring is connected to the inverter's AC INPUT terminals (L-L = 240Vac only) and the utility is used to charge the battery and power the load, i.e., household appliances. If the utility fails, e.g., in a power blackout, the battery kicks in (within 10ms) to power the inverter, which convert battery's DC voltage to inverter's output in AC OUTPUT terminals (split phase = 120Vac [N + L1 or N + L] and 240Vac [L1 + L2]). Mode#1 sees a 55.2V at the battery terminal, which is within charging voltage range for 48V Lead Acid, Gel, or AGM. So, for lithium, you need to lower the charging voltage (see User Manual for how). Energy Saving Mode (detect any load every 10 seconds, no load = go to sleep for 10 seconds) This is same as Mode#1 but the battery operation is set to energy saving mode. In energy saving mode, the inverter goes into sleep mode and wakes every 10 seconds to check what is the load demand. If the load demand is less than 10% of the inverter's rated power (10% of 3000W = 300W), the inverter will not supply power to the load. For example, if your load totaled 200W (e.g., a lamp and radio), inverter will not awake to power it. If your load is a water heater (e.g., 2000W), when the inverter awakes at the 10 seconds cycle it will stay awake to power the water heater. Powering a small shed light, without grid, is a likely working scenario suitable for Mode2. Inverter/Solar Priority This is similar to mode#1 but grid is not use (thus saving on electricity bill) to charge the battery, solar panels charge the batteries. If grid is connected, system in bypass mode. Solar charges the battery, not charge by grid (which only set battery terminal to 35V if solar is not connected). If grid is connected, operates in bypass mode, while solar charges the battery. If no grid (or grid fails), battery power the inverter and solar (if connected) charges the battery. When only grid is connected, the battery terminal reads about 35Vdc, so won't charge any type of 48V battery. In a site where there is no utility power, mode#1 is what you would most likely use. Mode#2 is useful if the whole household load never exceeds 200W, for example. This is an unlikely situation, so pure off-grid sites would be using mode#1. Mode#1 is useful for site with utility but has frequent power blackouts, so the power source automatically transitions to battery power on blackouts. Operational Notes When powered by solar alone, solar voltage must be 70-170Vdc (both PV and Battery switches must be in the On-position). With solar-only input, battery terminal measures about 48Vdc, which can charge your 48Vac battery. However, solar voltage fluctuates with the weather and if during operation the solar voltage dips below the minimum, connected appliances might be shut down. Therefore a solar voltage of about 100V might give a safer margin from weather fluctuations and give an above 48V at battery terminal to charge 48V battery. Appliances like lights might be alright with random on/off but desktop computer will not be and should never be connected when any inverter brand is on solar only.
