Choose the inverter around output, grid arrangement and load profile, then size the 48V battery for required runtime and surge support.
| System path | Inverter output | Battery path | Recommended application |
|---|---|---|---|
| SPH 10kW residential hybrid | 10kW, 120/240V split-phase | ALP 48V or a documented compatible battery | Typical homes, solar self-consumption and backup |
| SPH 18kW high-load hybrid | 18kW, 120/240V split-phase | ALP 48V or a documented compatible battery | Homes with larger HVAC, pumps or higher simultaneous loads |
| SPF / SPE off-grid | Model dependent | Supported 48V LFP or lead-acid bank | Cabins, workshops and independent power systems |

Capacity note: Growatt lists the ALP platform at 5–320kWh. The products shown here are common 5–30kWh packages; larger systems require the correct parallel architecture, controls, conductors and engineered protection.
Growatt SPH and ALP FAQ
What is the Growatt ALP battery?
ALP is Growatt's modular low-voltage LFP battery platform. The US ALP 5.0L-E2 module uses a 48V-class architecture, an IP66 enclosure and closed-loop communication with supported Growatt inverters.
How large can an ALP battery system be?
Growatt lists the ALP platform from 5kWh to 320kWh. Common residential stacks on this page are 5–30kWh. Larger parallel systems require the approved battery layout, cables, controls and an engineered design.
What is the difference between ALP and APX?
ALP is a 48V low-voltage battery used with compatible low-voltage hybrid and off-grid inverters. APX is a high-voltage battery for compatible battery-ready inverter families such as MIN XH-US. They are not interchangeable.
Which batteries work with Growatt SPH 10kW and 18kW inverters?
SPH supports Growatt ALP and other documented 40–60V lithium batteries; supported configurations may also use lead-acid batteries. Closed-loop lithium operation requires a compatible CAN or RS485 protocol, firmware and communication cable.
Can I use lead-acid batteries with a Growatt SPH inverter?
Growatt documents lithium and lead-acid support for this low-voltage inverter class. Battery settings, charge current, temperature compensation and low-voltage limits must be configured for the exact battery chemistry.
When should I choose SPH 10kW instead of 18kW?
Choose 10kW when the backed-up load calculation and motor-starting requirements fit within its output. Choose 18kW for larger simultaneous household loads. Battery discharge capability must be sufficient for the selected inverter.
Can multiple SPH inverters operate in parallel?
Supported SPH configurations can use up to six matched units in parallel. Use identical compatible models and firmware with the required parallel equipment, and follow the current Growatt design and commissioning documentation.
Can SPH inverters be used for a three-phase system?
A supported design can use three matched SPH units to form a three-phase system for selected small commercial applications. This is an engineered configuration; confirm voltage, phasing, controls, protection and utility requirements before purchase.
Can a generator charge an SPH battery system?
Supported SPH models include generator input and can use generator power for loads and battery charging. Generator voltage, frequency, waveform quality and charge-current settings must remain within the inverter's requirements.
Does SPH + ALP have UL 9540 system certification?
Specific SPH and ALP equipment combinations are offered as UL 9540 system configurations. Certification is model-specific, so confirm the inverter, battery modules and accessories against the current listing used by the permitting authority.
