Compact form factor, full hybrid capability

The transformerless design of the HF2430U80-H eliminates the bulky low-frequency transformer found in traditional inverter chargers, resulting in a unit that is 4.1 in. deep and weighs 17.6 lbs.—roughly a third of the weight of comparably rated transformer-based models. This makes it practical for installations where standard inverter chargers won't fit: shallow wall cavities, equipment racks, camper vans, boats, and outbuildings with limited panel space. Despite the compact footprint, it delivers a full 80A of solar charging current and a 6,000VA peak output rating for handling motor start loads.

Multiple charging and load modes

The HF2430U80-H supports multiple programmable charging source priorities—solar-first, grid-first, or hybrid simultaneous charging—allowing the system to be configured around available energy sources and utility rate structures. In off-grid mode it operates purely from solar and battery. When grid or generator AC input is present, the unit can charge the battery, pass power through to loads, or do both simultaneously based on user-defined mode settings. The 10ms transfer time between grid and battery modes keeps connected loads running continuously through source transitions.

Application scenarios

• Off-grid cabin or small home: 24V system powering lighting, refrigeration, communications, and small appliances with solar charging and optional generator backup.
• Mobile and marine installations: Lightweight transformerless design and shallow depth suit RV, camper van, and boat installations where weight and space are at a premium.
• Grid-tied backup for essential circuits: Grid or generator charging with 10ms battery transfer protects critical loads during outages without a separate transfer switch.
• Existing 24V system upgrade: Drop-in hybrid inverter charger for existing 24V battery banks that need solar integration without replacing the battery infrastructure.

System compatibility

The HF2430U80-H operates on a 24V battery bank across a 20–33Vdc input range and supports lead-acid, lithium-ion, and user-defined battery chemistries. Its single MPPT input accepts arrays up to 500Vdc open-circuit voltage with a 120–450Vdc MPPT operating range, allowing module strings to be sized for high-voltage series configurations without a combiner box. AC input accepts 90–140VAC at 50/60Hz from grid or generator sources. Communication interfaces include RS485, CAN, USB, and dry contact for BMS and monitoring integration, with an optional Wi-Fi/GPRS module for remote access. This unit is rated IP20 and requires indoor or enclosed installation; outdoor deployments need a suitable weatherproof housing.

Why choose the SRNE HF2430U80-H?

The SRNE HF2430U80-H is the right choice for 24V system builders who need a cETL UL1741 and CSA-certified hybrid solar inverter charger in a genuinely compact package—without trading away charging performance. Its 80A solar charging current, 500Vdc MPPT input, and 6,000VA peak output put it on par with full-sized competitors at a fraction of the weight and wall depth, making it particularly well-suited to mobile, marine, and space-constrained residential installations where a conventional inverter charger simply won't fit.
