Dual MPPT Solar PV Integration and Energy Management
The S5 hybrid inverter supports up to 10kW maximum PV input power, with two independent MPPT trackers and a maximum PV input voltage of 580V.
The dual-MPPT arrangement is useful for residential rooftops where modules are installed on different orientations, such as east-facing and west-facing roof sections.
Each tracker can operate independently within its specified voltage and current range, allowing the installer to design PV strings according to their electrical characteristics rather than combining unsuitable arrays.
A DC-oversized solar array may improve the available generation profile during lower-irradiance periods. However, the proposed array must be assessed against the inverter’s PV input limits, battery charging capacity and site-specific export requirements.
Self-Consumption and Battery Charging Strategy
The inverter’s internal Energy Management System coordinates photovoltaic generation, household consumption, grid interaction and supported battery charging modes.
Surplus solar electricity can be directed into the battery within the permitted operating limits. Stored energy can subsequently supply connected household loads according to the configured discharge strategy.
The included energy meter provides the measurement input required for energy-flow management. Remote monitoring and additional control functions depend on the installed communication hardware and supported software configuration.
For installers, the relevant design factors are the property’s measured consumption profile, available PV generation, charging window and required battery reserve—not battery capacity alone.
NEOVOLT 96V LiFePO4 Battery Architecture and Parallel Expansion
The BW-BAT-9.6P uses a 96V nominal DC battery architecture, with battery modules connected in parallel rather than series.
This arrangement maintains the nominal system voltage while increasing available energy storage capacity. It must not be confused with conventional 48V/51.2V battery platforms or multi-hundred-volt battery towers.
Inverter compatibility depends on the approved voltage range, BMS communication, charge/discharge limits and applicable firmware—not simply on whether two products use lithium iron phosphate cells.
Expandable Storage up to 57.6kWh
NEOVOLT specifies support for up to six BW-BAT-9.6P modules in parallel, providing a maximum nominal capacity of 57.6kWh.
This allows professional installers to plan additional battery storage where future consumption growth or a larger photovoltaic array justifies an expansion.
Additional modules require the manufacturer’s approved parallel connection arrangement, compatible BMS communication and the appropriate protection and connection equipment.
The inverter’s battery charging and discharging limits must also be checked when expanding storage. Adding battery modules increases stored energy but does not independently increase the system’s maximum AC output.
NEOVOLT additionally documents parallel operation of compatible single-phase hybrid inverters. Multi-inverter installations require their own approved wiring, communication and commissioning arrangements and are not included in this standard package.
Single-Phase Backup Power for Residential Electrical Circuits
The NEOVOLT S5 includes a dedicated backup output rated at 5kVA, with a manufacturer-specified transfer time below 10 milliseconds under supported operating conditions.
This allows the inverter to be incorporated into backup installations serving selected electrical circuits during a grid interruption.
Suitable applications may include lighting, refrigeration, networking equipment and other household loads whose combined demand remains within the permitted backup output.
Backup Design and Electrical Protection
For professional installers, backup capability must be established through the electrical design rather than assumed from the presence of a backup port.
The installation must account for:
- Continuous and starting power requirements of the protected circuits.
- Correct grid isolation and approved switching arrangements.
- Neutral and earthing requirements during backup operation.
- Available battery energy and configured minimum state of charge.
- Applicable national electrical and distribution-network requirements.
The manufacturer’s stated transfer time does not replace a site-specific assessment of sensitive equipment requiring uninterrupted power.
Installation Requirements and Professional Commissioning
The NEOVOLT S5 battery storage system is intended for installation by qualified solar PV installers and electrical contractors familiar with hybrid inverter systems and lithium battery storage.
Both the inverter and battery family are specified with IP65 enclosure protection. Nevertheless, mounting location, ambient conditions, clearances and equipment accessibility must comply with the applicable installation instructions.
Each BW-BAT-9.6P module weighs approximately 86kg, making mechanical handling and mounting-surface suitability important installation considerations.
Battery charging is permitted within the manufacturer’s specified temperature range. Installations in unheated garages, plant rooms or other environments exposed to low temperatures must account for these operating limitations.
Pre-Commissioning Checks
Before energising the system, installers should verify:
- PV strings: Correct polarity, open-circuit voltage, current limits and MPPT allocation.
- Battery connections: Approved parallel wiring, DC protection and BMS communication.
- Metering: Correct meter connections, direction of measurement and configuration.
- Grid settings: Country-specific protection parameters, export limitations and applicable grid requirements.
- Backup circuits: Load allocation, isolation, switching and protective-device coordination.
- System software: Compatible firmware and the required monitoring configuration.
For existing photovoltaic installations, the proposed integration must be checked against the installed inverter, distribution board and metering arrangement. The S5 should not automatically be treated as a universally compatible AC-coupled retrofit battery system.
