Summary of "Easy Solar vs Multi RS Solar: Which Victron Product is Better for You?"
Product(s) compared
-
Victron EasySolar
- With built-in solar regulator
- MPPT PV max input: 250V
- “EasySolar II” discussed
-
Victron Multi RS Solar
- All-in-one inverter/charger + solar unit
- MPPT PV max input: 450V
- RS series uses higher-frequency technology
The installer says both units can work well when matched to the right use case, but each has different tradeoffs.
Key features mentioned
EasySolar
- All-in-one unit with solar regulator built in
- 250V PV max input (vs. Multi RS’s 450V)
- Comes in 24V and 48V versions
- Offered in 3kVA and 5kVA inverter/charger sizes (per the speaker)
- Venus OS built in for operating/monitoring
- Remote programming/control via VRM Portal (internet required)
- Local monitoring via VictronConnect app
- Can be expanded:
- Parallel EasySolar units (“parallel these” mentioned)
- Add an external MPP when scaling beyond basic needs
- AC-coupled with grid/off-grid inverters for more usable load management
Recommended use cases (speaker’s view)
- “Tiny house”, “motor home”, and generally simple/basic off-grid setups
- Especially when staying around 24V (van use discussed later)
Multi RS Solar
- All-in-one design including PV + inverter/charger
- 450V PV max input
- Uses Victron high-frequency technology
- Comes as a 6kVA inverter (speaker claims this compared to 5kVA on EasySolers)
- Earth fault alarm included (important for the speaker’s Australia installations)
- Installation flexibility:
- Can wire 9–10 panels in a row (panel-brand-dependent), aided by higher string voltage
- Early model limitation: reportedly had only one MPPT tracker
- Newer model: has two trackers, allowing independent East/West (or North/West) arrays without combining them into one tracker
- AC coupling supported (per speaker)
- Remote programming:
- Speaker states much can be done via VictronConnect without a Cerbo
- Recommends adding a Cerbo for deeper control and easier remote programming
Limitations / tradeoffs mentioned
- Can’t parallel Multi RS units in the same way (speaker explicitly says this)
- 3-phase approach:
- Not parallel on single phase
- In 3-phase systems, you can use one unit per phase
- Usability note:
- Works best for simpler/off-grid use; becomes more “clunky” in complex setups
Pros / Cons (as stated)
EasySolar Pros
- Simple and “basic” for installers/users
- Good reliability/success history (years of installs referenced)
- Can be parallel-expanded and add more capability (to a point)
- 250V PV max still workable for many roof layouts (speaker references panel configurations + AC coupling strategy)
- Works well with AC coupling to reduce battery drain and manage loads overnight
EasySolar Cons
- EasySolar II generator auto-start: described as “clunky” to program/operate
- Fewer programming options and lacks certain screen-based options (speaker mentions “color screening” being unfortunate)
- Programming can be harder, sometimes requiring reverting to older methods (per speaker)
- No cross-phase parallelism: for 3-phase builds, recommended approach is mixing units across phases rather than spanning one system across all inverters
Multi RS Solar Pros
- Higher usability in the speaker’s opinion (overall conclusion)
- More PV headroom (450V):
- Easier stringing (fewer roof cable runs)
- More flexible East/West or mixed orientations using dual MPPT trackers (newer models)
- 6kVA output provides “a little more grunt”
- Supports AC coupling
- Two MPPT trackers on newer models improve partial shading/orientation flexibility
Multi RS Solar Cons
- Can’t parallel (single-phase parallel not supported)
- In the speaker’s complex full-house Victron ecosystem (Cerbo + VRM + many “smart” features), the Multi RS “works,” but felt like a step backwards for advanced integration
- Generator/AC charging capability:
- Speaker states early models lacked AC charging input
- No generator/grid AC input, and early configuration reportedly couldn’t AC-couple—this contributed to why they initially avoided it
- RV/motorhome startup voltage issue:
- Requires startup PV voltage ~80V, with the speaker noting ~120V minimum in practice
- Many vans/motorhomes can’t generate enough PV voltage, making it “really useless” for that application
- Suggests low-voltage (24V) systems are more beneficial for smaller vehicles; speaker prefers potentially 48V for battery swap convenience
Installation & user experience notes
- EasySolar
- Positioned as very “plug-and-play/basic”, especially for standalone off-grid or straightforward behavior (e.g., charging batteries from grid / weather-event scenarios)
- Multi RS
- Can be simple enough for basic off-grid use, but less straightforward for the speaker’s advanced “whole home” R&D
- For remote control, the speaker prefers adding a Cerbo for better controllability and programming convenience
Comparisons / decision guidance given
- Overall choice (speaker’s opinion): Multi RS Solar offers more usability than EasySolar for the situations they discussed.
- But the speaker recommends EasySolar for:
- Simple/off-grid
- 24V-oriented tiny house / motorhome style setups
- (With cautions about PV startup voltage depending on the unit/application)
- 3-phase guidance:
- Since neither unit is simply parallelable in the same way, the speaker suggests using different units across phases (example: one EasySolar on phase 1 and MultiPlus on phases 2–3).
- Heavy 3-phase appliance framing:
- The speaker argues most users should buy an energy-efficient welder rather than trying to build a “3-phase inverter path” just to support large loads.
Unique downsides / edge cases highlighted
- EasySolar II generator auto-start difficulty (“clunky” programming)
- Early Multi RS models reportedly missing AC charging input capability
- Motorhome/van PV startup voltage problem (~80V requirement; needs ~120V in practice), reducing usefulness for typical small-roof setups
- Advanced home integration: Multi RS felt less friendly/“clunky” in complex household R&D with deeper Victron ecosystem features
Ratings / numerical scores
- No formal numeric ratings (e.g., stars/points) were given.
Numerical specs mentioned
- EasySolar: 250V max PV, 3kVA / 5kVA, 24V / 48V
- Multi RS: 450V max PV, 6kVA
- RV/van context: ~80V startup concern; speaker says ~120V minimum in practice
- Panel stringing example (Multi RS context): 9–10 panels in a row
- MPPT orientation tradeoff (claimed): 5–10% capacity loss when East/West are combined on one MPPT tracker; dual trackers reduce this issue
Overall verdict (concise)
- Best general recommendation from the speaker: choose Multi RS Solar if you want more PV flexibility and practical usability (higher PV voltage, dual MPPT on newer models, more output) and you’re not focused on highly complex “full Victron smart home” integration.
- Choose EasySolar if you want a simpler, highly straightforward system—especially for 24V-based smaller builds—and you can tolerate potential EasySolar II generator auto-start quirks.
Speakers / perspectives
- Single speaker viewpoint throughout (no separate reviewers clearly delineated).
- The summary reflects the installer’s firsthand experience, plus their R&D observations and guidance.
